　　Throughout the global development of passenger cars, automatic transmission has been widely adopted. Its simple and easy to learn, convenient and intelligent characteristics bring drivers a more comfortable driving experience, and also better adapt to urban traffic.　　The implementation of the automatic shift function actually uses a gear shift switch instead of manual operation. The gear shift switch will control the shift fork and gear shift based on different engine speeds, vehicle speeds, and the driver's intention to press the accelerator. To achieve these automated operations, a shift switch requires a brain.　　The Hangshun chip M0 series automotive grade MCU HK32A040C8T3 is such a "brain", applied in gear shift switch schemes.

Unlock New Possibilities with NXP NMH1000 Magnetic Switch

　　Sensors collect critical data from the environment which can be turned into useful insights in almost every industry. But they have varying capabilities, reliability and levels of innovation which ultimately determine the experiences they can deliver. Our recently launched NMH1000 Magnetic Switch is designed to meet today’s market needs. It is a rare breed of magnetic sensor that replaces traditional bulky mechanical switches which are unsuitable for difficult environmental conditions. The three reasons to consider NHM1000 for your development include its distinctive features, flexible application and ability to easily onboard.　　Distinctive Features of the NMH1000　　The NMH1000 is most sensitive to the magnetic fields that vertically pass through the top-to-bottom surfaces. Input consists of a magnetic field ranging in strength from earth-bound background, up to maximum BGMAX. Its input processing consists of functional blocks such as a configurable state machine, analog-to-voltage conversion of the input and comparison to generate the output, arranged in linear succession.　　The sensor detects the absence of a magnetic field and outputs either a high or low state upon comparison with preset thresholds. It operates down to 1.2V supply voltage, which ensures longer shelf life with ultra-low power consumption (75 nA typ. @ 1 Hz sample rate). And it comprises a small DFN package, making it easy to integrate in very small areas. The NMH1000 also supports two operation modes: the standalone mode and the I2C user mode. In the standalone mode, the sensor’s interface to its host is extremely simple, while the I2C provides a more sophisticated interface to extract additional functions.　　Use Cases for the NMH1000　　A key differentiator of the NMH1000 sensor is its flexibility. It can be used for medical, industrial, consumer and smart home applications. These include CGMs, continuous glucose monitoring, drug delivery devices such as a Smart Inhaler, electronic wake-up systems, gas and water flow applications, anti-tampering metering, reed switch replacement and alarm systems. The sensor can add new experiences to some of these applications. For example, the NHM1000 is handy in situations where smoke detectors are out of reach with no easy way to test their functionality. In this case, the sensor can be used with a telescoping magnet for testing from ground level. This can be done by positioning the magnet near the smoke detector to put it into test mode.　　Another interesting use case of the NMH1000 is laptop power control. In this use case, a magnet is on the laptop monitor and the NMH1000 is on the keyboard. When the lid comes down, the magnet is close to the NMH1000, so its output will change state. This notifies the controller to switch off the display and disable the keyboard. And when the lid is opened, the magnet disappears and the NHM1000 will change the state to the other direction, telling the system to turn on the display and the keyboard.　　Onboard Easily with NMH1000 Freedom Shield Evaluation Board　　We developed the NMH1000 Freedom Shield Evaluation Board to help our customers evaluate the NMH1000 and kickstart their development speedily. The board can be connected easily to an NXP Freedom MCU board via the Arduino headers for evaluation. It has all the necessary headers, jumpers and signal test points to quickly evaluate the NMH1000 magnetic sensor.　　Users can connect the two boards to evaluate the NMH1000 magnetic sensor. This is possible with either a terminal program using the NXP Component Library or a standalone mode use case. These evaluation boards provide an intuitive way to change between the sensor’s standalone modes and the I²C interface for communication through jumper selections. At the same time, they provide test points that are typically used for evaluation.

Diodes’ Power Switch Enhances Power-rail Management in SSDs

　　Diodes' new single-channel high-side power switch features three different selectable slew rates so that wider capacitance loads can be handled while keeping inrush currents down.　　Diodes Inc. has launched a new versatile single-channel high-side power switch that features three different selectable slew rates so that wider capacitance loads can be handled while keeping inrush currents down, ensuring system stability. The DIODES AP22980 power switch is targeted at the solid-state data storage systems used in portable electronic equipment, computer hardware, and edge-based data center deployments.　　The N-channel MOSFET, with a built-in charge pump inside the AP22980, has an extremely low Rds(ON) of 5.1m? enabling loads reaching 6A while minimizing voltage drops and power losses in high current loading applications. By having a separate VBIAS pin, the minimum input voltage that it is capable of supporting is significantly lower, resulting in a wider input voltage range that can be covered—from 0.285V to 5.5V—enabling greater application flexibility.　　With 60?A (typical) quiescent supply current, the AP22980 is highly optimized for situations where keeping standby power consumption down is a priority. This device has an operational temperature range of -40°C to 105°C. If the junction temperature exceeds 150°C, an overtemperature protection mechanism is triggered.　　The AP22980 three-level selectable slew rate power switches are supplied in the compact W-QFN1520 package that takes up little board space and eases integration.

Scientists integrate opitcal components into chips designs

A group of researchers from MIT, the University of California at Berkeley and Boston University have developed a technique for assembling on-chip optics and electronic separately, which enables the use of more modern transistor technologies.The technique can be used by existing manufacturing processes and according to Amir Atabaki, one of the research scientists involved in the project, "The most promising thing about this work is that you can optimise your photonics independently from your electronics."Moving from electrical communication to optical communication is an attractive proposition for chip manufacturers because it could significantly increase chips' speed and reduce power consumption, an increasingly important advantage as chips' transistor count continues to rise:The integration of optical - or "photonic" - and electronic components on the same chip reduces power consumption. The optical communications devices currently on the market tend to consume too much power and generate too much heat to be integrated into an electronic chip such as a microprocessor.Atabaki and his colleagues have used a more space-efficient modulator design, based on a photonic device called a ring resonator."We have access to photonic architectures that you can't normally use without integrated electronics," Atabaki explains. "For example, today there is no commercial optical transceiver that uses optical resonators, because you need considerable electronics capability to control and stabilize that resonator."In addition to millions of transistors for executing computations, the researchers' new chip includes all the components necessary for optical communication: modulators; waveguides, which steer light across the chip; resonators, which separate out different wavelengths of light, each of which can carry different data; and photodetectors, which translate incoming light signals back into electrical signals.Silicon must be fabricated on top of a layer of glass to yield useful optical components. The difference between the refractive indices of the silicon and the glass is what confines light to the silicon optical components.Earlier work on integrated photonics involved a process called wafer bonding, in which a single, large crystal of silicon is fused to a layer of glass deposited atop a separate chip. The new work, in enabling the direct deposition of silicon on top of glass, uses polysilicon, which consists of many small crystals of silicon.Single-crystal silicon is useful for both optics and electronics, but in polysilicon, there's a trade-off between optical and electrical efficiency. Large-crystal polysilicon is efficient at conducting electricity, but the large crystals tend to scatter light, lowering the optical efficiency. Small-crystal polysilicon scatters light less, but it's not as good a conductor.Using the manufacturing facilities at SUNY-Albany's Colleges for Nanoscale Sciences and Engineering, the researchers tried out a series of recipes for polysilicon deposition, varying the type of raw silicon used, processing temperatures and times, until they found one that offered a good trade-off between electronic and optical properties."I think we must have gone through more than 50 silicon wafers before finding a material that was just right," Atabaki said.
