Description

The SP49 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 microcontroller, sensors, and convenient peripherals, the SP49 needs the addition of only a few passive components to form a complete TPMS sensor assembly. The device has been designed for lowest charge consumption making it ideal for battery powered applications.
