High-Integration, Intelligent Tire Pressure Sensor Revolutionizing TPMS Technology for Battery-Powered Applications
Infineon Technologies AG has introduced the XENSIV SP49 tire pressure monitoring sensor, combining automotive expertise with patented glass-silicon-glass MEMS sensor technology for intelligent tire functions like on-tire auto-position sensing, tire inflation assistance, tire blowout detection, and load detection.
The SP49 serves as a pin-to-pin replacement for SP40 TPMS products and offers hardware interfaces such as master/slave I²C, software-simulated UART, SPI, and PWM interfaces. It meets ASIL-A standards and provides a high level of integration for modern TPMS modules.
The SP49 is suitable for stand-alone remote pressure sensing solutions with low power consumption requirements. Its LF receiver with wake-up capability and sensitivity enables on-demand measurements in such applications.
