Infineon Technologies AG Tire Pressure Sensor (TPMS) SP400-15-11

XENSIV(TM) - SP400-15-11 Automotive Tire Pressure Monitoring Sensor with pressure range 100 to 1400 kPa, truck derivative The Infineon XENSIVTM SP40PLUS provides a very high level of integration, and is optimized to perform all of the functions necessary to implement a state-of-the-art Tire Pressure Monitoring System (TPMS) sensor module. With its integrated micro controller, sensors, and convenient peripherals, the SP40PLUS needs the addition of only a few passive components and a battery to form a complete TPMS sensor assembly.
