NXP has dual magnetic sensor for safety critical automotive applications

1 min read

Targeted at safety critical automotive applications where a mechanical angle needs to be measured, NXP's KMA220 is a dual magnetic sensor offered in a single package, which the company claims simplifies the assembly process and lowers cost.

Operating in a simple disk magnet configuration with no need for a pcb or external components, the device is particularly suited to throttle control applications where a redundant system solution is required. According to NXP, it is fully calibrated and ready to use, and incorporates three capacitors in addition to two sensors dies and two signal condition ASICs. The KMA220 utilises NXP's ABCD9 technology, which is said to significantly improve performance compared to previous sensor products with integrated ASICs. The KMA220 is also qualified according to the Human Metal Model (HMM) standard with excellent electrostatic discharge protection and EMC performance. "Building on the success of the KMA210, the KMA220 is a new addition to our existing family of position sensors for the automotive industry and offers customers a package that they can't get anywhere else," noted Stephan zur Verth, vice president and general manager, NXP. "As a next step, we plan to release a single sensor product in the same package which means that our customers will be able to use the same assembly process for all applications, making it easy for them to choose and install the right solution for their products."
