Active250 in stock

Overview

The SP370231060 is a highly integrated Tire Pressure Monitoring Sensor (TPMS) and Passive Entry/Start (PEPS) IC designed for automotive safety systems. It features a dual-band transmitter capable of operating at 315MHz and 434MHz to meet international RF standards. The device is engineered to operate reliably in harsh environments with a wide temperature range from -40degC up to 125degC.

Why Choose This Part

This IC combines a pressure sensor interface, temperature sensor, and RF transmitter into a single 14-SOIC package, reducing PCB footprint. Its wide supply voltage range of 1.9V to 3.6V supports operation from various lithium coin cell batteries, while the automotive-grade temperature rating ensures performance under extreme wheel-well conditions.

Applications

Tire Pressure Monitoring Systems (TPMS)
Real-time monitoring of tire pressure and temperature to enhance vehicle safety and fuel efficiency.
Passive Entry and Passive Start (PEPS)
Enabling secure keyless entry and ignition systems through low-power RF communication.
Remote Keyless Entry (RKE)
Standard automotive remote control functionality for locking and unlocking vehicle doors.

Getting Started

Designers should refer to the Infineon SP37 family evaluation kits to calibrate the pressure sensing thresholds and optimize the antenna matching for 315MHz or 434MHz operation. Development requires a compatible embedded toolchain for the integrated microcontroller core and specialized RF testing equipment for FCC/ETSI compliance verification.
