Ameya360:Nordic Semiconductor Multi-function PMIC Simplifies System Design

　　Nordic Semiconductor is expanding its power management IC (PMIC) portfolio by releasing a third PMIC in mid-2023. The nPM1300 expands the company’s PMIC offering by adding support for both charging of larger batteries and four regulated power rails.　　Optimized for efficiency, the compact nPM1300 (3.1-by-2.4mm WL-CSP or 5-by-5mm QFN) is digitally configurable through an I2C-compatible Two Wire Interface (TWI). The digital interface provides access to several system management functions that are usually implemented as discrete functions in Bluetooth Low Energy (LE) embedded designs, such as hard reset, battery fuel gauge, system-level watchdog, power loss warning, and recovery from failed boot.　　“Nordic entered the PMIC market because existing power management solutions were not optimized for compact, ultra-low power IoT applications. Available PMICs leave it up to the designer to implement vital functionality using discrete components—functions that naturally belong inside a PMIC and can be implemented at almost no cost,” says Geir Kjosavik, Product Director – PMIC, Nordic Semiconductor. “So, we did just that. Nordic’s customers will be delighted to have access to on-chip functions that enhance product safety and provide additional ways of conserving battery energy.”　　The nPM1300 is designed to provide highly efficient power regulation for Nordic’s nRF52 and nRF53 Series advanced wireless multiprotocol Systems-on-Chip (SoCs). The PMIC’s four regulated power rails and battery charger make it ideal for compact and advanced IoT products based on, for example, an nRF5340 SoC host and multiple peripheral functions such as sensors. Examples include advanced wearables and portable medical applications.　　The nPM1300 PMIC operates from an external power supply of 4V to 5.5V and can operate from a battery voltage down to 2.4V. Two power rails are regulated by separate DC/DC buck converters that are configurable between 1V and 3.3V and up to 200mA maximum current. The other two power rails operate as load switches—switching currents of up to 100mA from external sources—but can also perform as Low Drop Out (LDO) voltage converters when powered directly by the nPM1300. When operating as LDOs, these power rail outputs are configurable between 1V and 3.3V with a maximum output current of 50mA. The unregulated input voltage is also available as an output from the nPM1300.　　The nPM1300 charges single-cell Li-ion, Li-Pol, and LiFePO4 batteries with a linear charging module that supports up to 800mA charge current. The termination voltage is programmable from 3.5V to 4.45V. The battery charger features automatic thermal regulation with programmable maximum chip temperature during charging to enable simple thermal management that can be adapted to any system requirement.　　The nPM1300 brings other new advanced features to Nordic’s PMIC range including: USB port detection with automatic current limits of 100mA or 500mA through standard USB or up to 1.5A through USB-C PD (Power Delivery); dynamic power path management which automatically switches to battery power if a mains power connection is removed; voltage, current and temperature monitoring for accurate fuel gauging; and ultra-low current hibernate mode with a programmable wake-up timer in addition to the other system management features already mentioned. The PMIC also features three LED drivers and five GPIOs that can be re-purposed to direct control lines to time-critical control functions as an alternative to serial commands.　　The nPM1300 is available for limited sampling now, and will be available to order from Nordic’s distributors mid-2023.

Nordic Semi Rolls Integrated Module of IoT

　　After three years in development by teams in Finland and Norway, Nordic Semiconductor introduced a system-in-package (SiP) module for low-power Internet of Things (IoT) applications.　　Nordic's nRF91 integrates an LTE cellular model with narrow-band IoT (NB-IoT) connectivity in a 10x16x1.2mm package. It also incorporates a transceiver, RF front end, dedicated application processor, flash memory, power management and crystal and passive components.　　After announcing last month that lead customers were already sampling the nRF91, Nordic revealed details of the device at an event in Oslo last week. During the event, Nordic also demonstrated the nRF91 operating on the Verizon Wireless Network in the U.S. and on the Telia network in Norway.　　The nRF91 SiP is aimed at secure, low power, cellular connected IoT systems. Jointly developed by Nordic’s specially assembled cellular design team in Finland, and low power team in Norway, the chip was developed from scratch to optimize the power, cost and size savings enabled by the new LTE-M and NB-IoT cellular standards.　　Nordic says the custom SoC combines the benefits of traditional cellular modules — including tele-regulatory and cellular certifications — with ease-of-use and the smallest form factor ever seen in the cellular industry to date. According to the company, the module has up to three times smaller footprint than other solutions on the market and a lower external bill of materials (BoM).　　The module features 23 dBm output power and a -108dBm sensitivity receiver in the 700MHz-2.2GHz range. It also has a throughput of up to 360kbps with LTE-M and 60kbps for NB-IoT.　　Nordic said it worked with Qorvo as a strategic partner for both the RF front end and the SiP development and manufacturing. The nRF91 Series supports global operation with a single SiP variant is a result of the combination of Nordic’s multimode LTE-M / NB-IoT modem, SAW-less transceiver and a custom RF front-end solution from Qorvo.　　With security becoming increasingly a critical consideration in IoT systems, the company says it needed to have a processor with a built-in security platform.　　"Security is the main reason we went for the Arm Cortex-M33 processor and Arm CryptoCell-310 security IP," said Peder Rand, product manager for cellular IoT at Nordic, in an interview with EE Times. "Its architecture brings the TrustZone technology to the embedded space."　　This integration enabled an entire low power cellular IoT application to be implemented on an nRF91 SiP. The built-in host processor features TrustZone for Armv8-M, helping secure application data, firmware, and peripherals using an isolated, trusted execution environment across the CPU and system.　　The SiP also features built-in support for positioning via an integrated assisted GPS (A-GPS) solution that combines cellular and GPS technology to deliver fast and accurate positioning.　　Rand said key target areas initially for the device are in asset tracking, predictive maintenance and healthcare. He said people want to know where their "things" are and in what condition they are in.  In healthcare, Nordic is aiming for the professional monitoring of patients’ vital signs in their own homes.　　Rand said that in these applications, small physical size, low power, reliable connectivity and security are essential. The company expects general sampling in the middle of this year and volume production by the end of 2018 with lead customers.　　Nordic says Telia and Verizon are key network partners. Rand said that while Nordic’s business model is to sell electronic components to OEMs and ODMs, these customers need a carrier that enable them to deliver IoT connected products.　　Telia says it is experiencing an unprecedented demand for dedicated IoT connectivity represented by LTE-M and NB-IoT. These technologies enable products and services that wouldn’t otherwise be possible. In Nordic’s press release, it added that access to components has so far been scarce and has hindered large scale commercial launches.
