The KMA220 is fully calibrated and ready to use, and incorporates three capacitors in addition to two sensors dies and two signal conditioning ASICs. This, combined with its dual nature, reduces system cost for customers and simplifies the assembly process. To achieve redundancy in throttle applications, car manufacturers have previously had to install two single sensors on a leadframe or onto a PCB, bending them to fit -- typically requiring an expensive ring magnet configuration to operate. With the dual KMA220 sensor, only one simple installation is required.
The KMA220 uses NXP's unique ABCD9 technology, an automotive platform at the cutting edge of analog mixed-signal integration. This technology is based on NXP's CMOS 14 process and significantly improves performance compared to previous sensor products with integrated ASICs. The KMA220 is also qualified according to the new HMM (Human Metal Model) with excellent electrostatic discharge (ESD) 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," explains Stephan zur Verth, vice president and general manager sensor business, NXP Semiconductors. "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."
NXP's automotive sensor family is exceptionally robust, capable of operating at temperatures of up to 160 degrees C, compared to the industry average of 150. This is vital for use in EGR (exhaust gas recirculation) applications, where every degree counts.
