Overview

The SP370251160XTMA1 is a highly integrated tire pressure monitoring sensor (TPMS) from Infineon, designed for high-volume automotive tire pressure monitoring systems. It combines a pressure sensor, accelerometer, temperature sensor, and microcontroller into a single package to provide real-time tire diagnostics. The device operates reliably across a wide temperature range of -40 degC to 125 degC, meeting the rigorous demands of vehicle wheel-well environments.

Why Choose This Part

This sensor offers a high level of integration, significantly reducing the bill of materials for TPMS modules. Its digital output and integrated MCU allow for sophisticated power management and data processing before transmission, extending battery life in the tire. The robust -40 degC to 125 degC operating range ensures functional safety in extreme climate conditions.

Applications

Direct Tire Pressure Monitoring Systems (TPMS)
Installed inside the tire to provide accurate, real-time pressure data directly to the vehicle ECU via wireless link.
Vehicle Dynamics Systems
Utilizing the integrated accelerometer to detect wheel motion and rotation speed for motion-triggered reporting.
Fleet Management
Enabling wireless tire health monitoring in heavy-duty commercial vehicles to prevent blowouts and improve fuel efficiency.

Key Specifications

Output Type Digital
Sensor Type Tire Pressure Monitoring (TPMS)
Operating Temperature -40degC ~ 125degC

Getting Started

Developers should use Infineon's TPMS evaluation kits and the accompanying SP37 programming tools to configure the sensor's firmware and RF transmission parameters. Calibration and test procedures must be performed using a pressure-controlled chamber to ensure accuracy across the full -40 degC to 125 degC range.
