NXP Launches new angular sensor compliant with SENT standard for automotive sensor applications; high-accuracy powertrain applications
NXP Semiconductors N.V. released the KMA215, a programmable angle sensor with digital output, which is compliant with the most recent Single Edge Nibble Transmission for Automotive Applications (SAE J2716 JAN2010 SENT) standard. SENT is a point-to-point scheme for high-resolution data transmission from a sensor to a controller. Suitable for all automotive applications where a mechanical angle needs to be measured, the new KMA215 is particularly valuable for all power train applications where high accuracy and robustness is essential, NXP says.
The KMA215 is also prepared for the future, already supporting 12bit High-Speed transmission with doubled frame rate, which is under consideration for future SENT releases.
The KMA215 angular sensor addresses the rapidly evolving needs of the automotive industry, offering customers a superior EMC performance at a reduced cost, while meeting the most recent SENT protocol. Building on the success of the KMA210 and KMA220, the KMA215 is a strong addition to NXP’s family of automotive sensors and offers a robust and reliable solution for the automotive industry, supporting the need to increase the number of electronic applications in the car by enabling multiple information transfer via a single interconnection.—Guenter Reiniger, marketing manager, automotive sensors at NXP Semiconductors
Completely calibrated and ready to use, the KMA215 combines full sensor systems including capacitors in a single package. It meets the most recent SENT protocol, the standard interface in motor management control units, and delivers a modern mid-sized signal sensor architecture, ensuring accurate digital data processing and transmission.
The KMA215 is designed to meet the needs of the worldwide automotive market by complying with the SENT digital protocol, and combines NXP’s latest MR and ABCD9 technology. The angular sensor has a push-pull output with pulse shaping, which helps reduce its emission profile without external components.
NXP’s automotive sensor family enables reliable high-resolution data transmission. The KMA215 comprises Cyclic Redundancy Check (CRC) and Error Detection and Correction (EDC) protection, as well as magnet loss and broken bond wire detection. It operates at temperatures of up to 160 °C, in comparison to the industry average of 150°C. This is vital for use in EGR (exhaust gas recirculation) applications, where every degree in temperature counts.
The release of the KMA215 further supports NXP’s vision of connecting the car.
