NXP Improves Performance of Automotive Applications

NXP Semiconductors N.V. has released a new generation of automotive position sensors, the KMA210, which incorporates the company's latest magnetoresistive sensor chip and a unique signal conditioning ASIC developed in its advanced Silicon on Insulator (SOI) ABCD9 process technology. It is the first of a new magnetic sensor family in a full system-in-package solution that requires no external components.

The KMA210 is designed to improve the overall performance and increase robustness in automotive applications, from electronic steering and active suspension to automatic headlight adjustment. The device is especially recommended for under-the-hood power train applications, throttle control and air control valve measurements. In addition, the sensor’s robustness in high temperature ranges (up to 160°C) makes it ideal for Exhaust Gas Recirculation (EGR) applications.

NXP’s magnetoresistive position sensors enable a safer, cleaner and more comfortable ride. To support global mandates to regulate CO₂ in cars, KMA210 sensors can aid in the regulation of the engines untreated emissions.

By designing the Signal Conditioning ASIC in ABCD9, NXP’s proprietary automotive grade Silicon on Insulator (SOI) technology based on 140nm CMOS, the Electromagnetic Compatibility (EMC) performance is significantly improved compared to previous sensor products with integrated ASICs. The device contains two embedded capacitors within the same package which enables system cost reduction as no printed circuit boards or external filter components are required for operation. With respect to robustness, the KMA210 sensor is qualified according to the new HMM (Human Metal Model) and therefore extremely robust with excellent electrostatic discharge (ESD) behaviour. The sensors are fully temperature compensated and ready for use.
