NXP magnetoresistive sensors KMA2xx series Improve the ride with fully integrated angular sensor systems These advanced sensors, with their ability to help reduce emissions, increase vehicle stability, and add driver-independent control functions, create a safer, cleaner, more comfortable ride, and help realize the future of green cars. Key features `` Contactless angle measurements up to 180° `` High temperature range up to 160 °C `` Automotive qualification according to AEC-Q100 `` Excellent EMC and ESD performance `` No external components required `` Overvoltage protection up to 16 V `` Reflow capable due to MSL1 The NXP KMA2x magnetoresistive (MR) angular sensors support the worldwide commitment to reduce CO2 emissions from cars. They help OEMs enhance their engine concepts, creating new ways to meet environmental targets. Key benefits `` Insensitive to - magnetic drift over lifetime - magnetic drift with temperature - mechanical tolerances - mechanical shifts caused by thermal stress In diesel engines, they can assist with particle filter regeneration by throttling the intake air and thereby reducing the amount of emitted particulate mass. Applications `` Throttle position `` Pedal position `` Active suspension `` Wiper position `` Electronic steering In electronic valve actuators, for example, they can help reduce untreated emissions through optimization of the combustion air supply and the recirculation rate of exhaust gas. As part of the load control unit on drive-by-wire engines, the sensors can enable a range of features, including driverindependent control of air intake, control functions for idle speed and cruise control, and Electronic Stability Program (ESP) functions. Fully integrated single angular sensor KMA210 This is the first in a new family of system-in-package solutions that require no external components. It integrates NXP’s latest magnetoresistive sensor chip, produced in six-inch technology, plus a unique signal conditioning ASIC, developed in ABCD9 technology. It is specially designed to improve overall performance and increase robustness in automotive applications. The solution also contains two embedded capacitors in the same package. This lowers cost as no PCB or external filter components are required for operation. MR sensor ABCD9 ASIC Capacitors VDD GND Vout Highlights `` The ABCD9 technology, with its Silicon-on-Insulator process, is an automotive-grade technology based on NXP’s CMOS14 process. `` Electromagnetic Compatibility (EMC) performance is significantly enhanced compared to previous sensor products with integrated ASICs. `` 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) behavior.

It is intended for all applications requiring redundant sensor solutions as e.g. throttle applications. The sensor is equipped with two MR sensor dies and two ASICs providing two statistical independent output signals. Furthermore the block capacitor for the supply line and the two capacitors for both outputs are inside the package as well. KMA220 does not require any external components for stable operation. Two MR sensors Two ASICs KM A22 0 Three Capacitors aaa-001711 Highlights `` Uses the KMA210 ASIC, do it delivers the same key performance parameters, including excellent performance for EMC and ESD. `` Enables significant cost reductions by making it possible to use a disc magnet instead of a ring magnet configuration. Distortion from external magnetic fields is negligible because the sensor operates in magnetic saturation for all angles.
