SP370-23-156-0

The SP37 is a highly integrated device which performs all necessary functions for a Tire Pressure Monitoring System (TPMS) wheel module suited for high-volume applications. The device contains the sensing elements, the microcontroller, the LF receiver, the RF transmitter and more in one package requiring only few external components to complete a TPMS module. Since 2003, more than 150 million TPMS sensors of our continuously improved product generations were sold worldwide. The sensor design of the SP37 is based upon Infineon’s patented bulk micromachined sensing technology which allows highly reliable measurements in harsh environments. The SP37 measures pressure, radial acceleration, temperature and supply voltage. The device is compliant to the RoHS standard, with a pressure range from 100 up to 1300kPa. Numerous embedded firmware functions and a development kit enable fast development cycles.
