The SP370251160XTMA3 from Infineon is a Tire pressure sensor in 14 pin DSOSP package. This 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, microcontroller, LF receiver, RF transmitter and more in one package requiring only few external components to complete a TPMS module. The SP37 measures pressure, radial acceleration, temperature and supply voltage.
