1 Product Description

1.1 Overview

The SP30 Tire Pressure Monitoring (TPM) Sensor represents Infineon’s standard pressure range TPM sensor. The SP30 offers a high level of integration by including a microcontroller, signal conditioning and LF-input stage to meet market demands for flexible, customer specific solutions and overall system cost reduction.

The sensor design is based on Infineon’s proprietary and patented solutions for high reliability measurements in harsh automotive environments. Its predictable and stable quality is proven in high volume applications.

The SP30 measures pressures up to 900kPa, temperature, supply voltage and acceleration (optional), and by integrating these functions with an ASIC in one package, Infineon has developed the ideal product for standard pressure TPM applications.
