<span style='color:red'>NOVOSENSE</span> Launches NSIP3266 Full-Bridge Transformer Driver with Integrated Crystal Oscillator, Simplifying Isolated Driver Power Supply Design
Trade news

NOVOSENSE Launches NSIP3266 Full-Bridge Transformer Driver with Integrated Crystal Oscillator, Simplifying Isolated Driver Power Supply Design

　　NOVOSENSE today announced the launch of the NSIP3266 full-bridge transformer driver with integrated crystal oscillator, multiple protection functions and soft start support, which can be widely used in isolated driver power supply circuits in automotive on-board chargers (OBCs), traction inverters and charging piles, photovoltaic power generation and energy storage, server power supply and other systems. NSIP3266 supports a full-bridge topology with a wide range of inputs, and with clever pin and function design, it greatly simplifies the design of isolated driver’s power supply circuits, facilitating system manufacturers to optimize system circuits and shorten product time to market.　　Currently, isolated driver's power supply in high-voltage systems is available in three architectural forms: centralized, fully distributed, and semi-distributed. Centralized architecture has only one stage of power supply, and the auxiliary power input voltage has a wide input range, requiring closed-loop operation. At the same time, the transformer design is complicated, and especially when a single low-cost isolated power supply is used, there are problems of multi-output load regulation and long wiring, which increase the difficulty of system design and debugging.　　Fully distributed architecture uses independent isolated power modules to supply power to isolated drivers. The advantage is that 1-to-1 power supply and targeted protection can be achieved for isolated drivers, but a corresponding number of isolated power modules need to be configured, and the system cost is high.　　Semi-distributed architecture adopts a balanced strategy. Through a two-stage auxiliary power architecture, the first stage uses devices with a wide input voltage range to generate regulated rails, and the second stage can be a compact open-loop form using other devices to provide isolated power supply for isolated drives. Semi-distributed architecture is gaining popularity among engineers because of its simplicity in design and balance of system cost, performance, and protection requirements.　　Simplified circuit design with full-bridge topology　　NOVOSENSE's NSIP3266 full-bridge transformer driver is designed for semi-distributed architecture with isolated driver power supply. Common topology options for semi-distributed architecture include push-pull, LLC, and full-bridge. NSIP3266 adopts full-bridge topology. Compared with other solutions, the principle of full-bridge topology is simple, the transformer structure does not require a center tap, the working principle does not involve the design and selection of external L and C, and the peripheral BOM is often minimal. At the same time, the full-bridge topology is more tolerant to transformer design, including leakage inductance and parasitics, which saves engineers' efforts in system design and debugging.　　Ingenious design releases MCU resources　　It is worth mentioning that NSIP3266, through the internal integrated crystal oscillator circuit and RT pin design, allows engineers to complete the switching frequency configuration with only external resistors, achieving decoupling of MCU control and more flexible layout. At the same time, it can still provide safe power supply when the MCU fails, promoting higher system safety. In addition, the built-in soft-start function of NSIP3266 also eliminates the need for MCU control. While not requiring MCU domain routing, it saves secondary-side current limiting resistors, greatly simplifying board design and improving architectural flexibility.　　Wide voltage input and comprehensive protection　　NSIP3266 supports a wide operating voltage range of 6.5V~26V. No additional TVS protection tube is required in the system circuit, allowing engineers to choose the pre-stage power supply more flexibly. In addition, NSIP3266 provides multiple protection functions, including undervoltage protection, overcurrent protection, over-temperature protection, etc. The comprehensive protection functions enable engineers to focus on the optimization and innovation of the core system functions, and to design the system quickly and efficiently to meet the reliability requirements.　　Packaging and selections　　NSIP3266 is available in EP-MSOP8 package (3.0 x 3.0mm x 0.65mm, with thermal pad). The industrial version, NSIP3266-D, and the automotive version, NSIP3266-Q1, which meets the requirements of AEC-Q100, will be mass-produced in the first half of 2025. Please contact NOVOSENSE's sales team (sales@novosns.com) for product details or to request samples.　　Rich isolation products meet diverse needs　　With its expertise and leadership in isolation technology, NOVOSENSE provides a series of isolation and "isolation+" products covering digital isolators, isolated sampling, isolated interfaces, isolated power supply, and isolated drivers. NSIP3266 is a new addition to NOVOSENSE's isolated power supply family. NOVOSENSE also offers a selection of other cost-effective and high-performance, high-integration options, including: the NSIP605x series of push-pull transformer drivers; the NSIP88/89xx and NIRSP31x series with integrated transformers and multi-channel digital isolators; the NSIP83086 isolated RS485 transceiver and the NSIP1042 isolated CAN transceiver with integrated transformers and isolated interfaces.

<span style='color:red'>NOVOSENSE</span>'s NCA1044-Q1 CAN Transceiver Successfully Passes the IBEE/FTZ-Zwickau EMC Certification
Trade news

NOVOSENSE's NCA1044-Q1 CAN Transceiver Successfully Passes the IBEE/FTZ-Zwickau EMC Certification

　　NOVOSENSE announced that its newly launched NCA1044-Q1, an automotive-grade CAN transceiver, had received the EMC certification test reports from IBEE/FTZ-Zwickau, a prestigious European testing organization. NCA1044-Q1 successfully passed all test items. NOVOSENSE now can provide the test report to support automakers in streamlining their system certification process and accelerating their product launches.　　CAN transceivers are commonly used in automotive CAN bus networks typically for critical control and diagnostics functions, such as battery, motor control, electronic control, braking, steering, and airbag systems. These applications are prone to various sources of electromagnetic interference (EMI), including battery, motor and electronic control systems for EVs, engine, frequency converter and wireless communication devices. Such disturbances can adversely affect data transmission, leading to signal errors or system failures, and even compromised system safety.　　In addition, due to the long distance of CAN bus wiring in automotive systems, CAN transceivers can easily radiate noise through the CAN bus acting as an antenna. This can result in radiated emission and conducted emission from modules or the entire system that exceed the requirements for vehicle. Therefore, CAN transceivers that provide good electromagnetic compatibility (EMC) performance are essential for ensuring system reliability.　　Full compliance with IBEE/FTZ-Zwickau certification　　Given the critical role of CAN transceiver's EMC performance in automotive safety, countries or regions have established stringent automotive EMC standards and certification procedures for automakers to follow. For example, both the SAE J2962 standard and the European IBEE/FTZ-Zwickau certification set clear requirements for the EMC performance of automotive electronics.　　The IBEE/FTZ-Zwickau certification is carried out according to the IEC 62228-3 standard. Compared with SAE J2962, IEC 62228-3 excludes the effects of peripheral circuits, focuses more on the EMC property of the CAN transceiver itself, and specifies higher performance level requirements. The IEC 62228-3 standard is also extensively adopted by automakers outside of Europe. The IBEE/FTZ-Zwickau certification includes four tests: Emission RF Disturbances, Immunity RF Disturbances, Immunity Transients, and Immunity ESD. NCA1044-Q1 from NOVOSENSE successfully passed all four tests.　　Industry-leading interference immunity　　NCA1044-Q1 features an ingenious circuit design that addresses the issue of output signal errors caused by abnormal high-voltage interference affecting its output circuit. This enhances its EMC performance, helping customers substantially reduce their EMC design complexity, simplify peripheral components, and lower costs.　　Furthermore, NCA1044-Q1 boasts industry-leading interference immunity. According to IEC 62228-3, when external RF noise at different frequency bands couples to the CAN bus, a higher pass-through power indicates stronger interference immunity. This means a lower risk of errors in the system.　　Even without the use of a common-mode inductor filter on the bus, NCA1044-Q1 from NOVOSENSE can still meet the highest power requirements specified in the standard (as shown in Figure-1 and Table-2). Although this test is typically not required at the application level, NCA1044-Q1 still successfully passed the test. This capability helps users reduce peripheral circuits, lower costs, and enhance system robustness.　　Packages and selection　　NCA1044-Q1 is now in mass production and is available in SOP8 and DFN8 packages. Compliant with the AEC-Q100 Grade 1 requirements, it operates in a wide temperature range from -40°C to 125°C, and provides over-temperature protection. NCA1044-Q1 also supports TXD dominant timeout function and remote wake-up in standby mode.

　　With the continuous pursuit of high-precision, high-performance motor control technology, the ability of resolvers, as one of its core components, to accurately measure angular position and rotational speed becomes particularly important.　　However, the special requirements of resolver drive circuits have always been a technical bottleneck in the development of the industry. To address this challenge, NOVOSENSE recently released the new NSOPA240x series of operational amplifier, which is designed to simplify circuit design and improve system robustness, bringing innovative solutions to resolver drive applications.　　As electromagnetic sensors that can be used to accurately measure angular position and rotational speed, resolvers are widely used in industrial motor controls, servos, robots, and powertrain units in electric and hybrid vehicles. Particularly in electric vehicles, resolvers provide motor control algorithms with precise and stable position information, which is critical to ensuring ideal performance in a wide range of driving conditions. Through their unique operating principle, resolvers provide real-time and accurate feedback on the rotor angle and speed, enabling electric vehicles' motor control algorithms to accurately adjust the current output for smooth driving and instant response. In addition, resolvers' high temperature resistance, simple and reliable mechanism, compact size and low cost make them adaptable to the compact design requirements of electric vehicles and reduce overall costs.　　In practice, the design of resolver drive circuits faces multiple challenges. First, the requirements for high current output and high slew rate must be met to ensure a stable excitation signal for resolvers. Second, simplifying circuit design and improving system robustness are also important issues faced by engineers. In addition, complex noise environments and stringent safety requirements bring more difficulties to the design.　　With their excellent high gain bandwidth and slew rate, as well as continuous high output current drive function, NOVOSENSE's NSOPA240x high-current output operational amplifiers meet the stringent requirements of resolver primary coils for low-distortion and differential high-amplitude excitation. More importantly, NSOPA240x integrates internal thermal shutdown and overcurrent production, which not only optimizes the circuit design and reduces the system cost, but also significantly improves the overall system reliability and performance.　　The automotive version of the NSOPA240x series meets the reliability requirements of AEC-Q100 Grade 1 and can work in harsh environments of -40~125°C. Different channel versions are available to meet different customer needs, with TO252-5 package for single-channel and HTSSOP14 package for dual-channel, as shown in the table below.　　High current output capability - adapt to various resolver primary coil drives　　Output current capability and output swing are among the most important indicators to measure the driving capability of power amplifiers. The relationship between load current and output swing directly determines the dissipated power in driving operational amplifiers. The excitation primary coil of a resolver usually has a very low DCR (DC resistance), typically less than 100Ω, so a strong current output capability up to 200mA is required to drive the coil. NSOPA240x is designed with a maximum continuous output current capability of 400mA, fully meeting the drive requirements of various resolvers.　　High output slew rate - ensure undistorted primary coil excitation signal　　Slew rate is one of the most important performance indicators reflecting the dynamic response of an operational amplifier, and the minimum requirement for undistorted sinusoidal signals is shown in the following formula:　　Different types of resolvers have different requirements for the amplitude and frequency of the excitation signal. Taking a 7Vrms, 10kHz excitation signal as an example. According to the calculation results of the above formula, the minimum slew rate required to ensure no distortion is about 0.6 V/μs. With a slew rate of 5.5 V/μs, NSOPA240x meets most application requirements for resolver drives.　　Integrated current limiting protection and overheating protection - improve resolver system reliability, and reduce complexity and cost　　For the power level of several hundred mA at the primary drive end of a resolver, perfect protection measures must be taken, otherwise the system will be seriously threatened or even burned due to overheating and other reasons. NSOPA240x integrates a thermal shutdown protection function. When the chip junction temperature exceeds 173°C, the device will be disabled and the occurrence of a thermal shutdown event will be indicated by the OTF/SH_DN status. To prevent repeated triggering, the overtemperature shutdown function has a temperature hysteresis, where the junction temperature needs to fall back to 155°C before the device is re-enabled and the state of the OTF/SH_DN pin changes to indicate that the thermal shutdown event has stopped.　　As shown in the figure below, NSOPA240x can provide customers with system-level functional safety and simultaneously indicate short circuit to power and short circuit to ground.　　In addition, each operational amplifier in the chip has current limiting protection for the PMOS (high side) and NMOS (low side) output transistors, because overcurrent may be found on the high side or the low side. And two dedicated pins (as shown in the red box in the figure) are provided to distinguish between high side overcurrent and low side overcurrent, corresponding to the applications of short circuit to ground and short circuit to supply voltage respectively. When the output current returns to normal, the indicator pins will be released synchronously, allowing the system to easily cope with short circuit test scenarios similar to those specified in the ISO 16750 standard.
