High-Pressure Tire Pressure Monitoring Sensor (TPMS) Family

FXTH8715

Roll over image to zoom in

The FXTH8715 high-pressure family of tire pressure monitoring sensors (TPMS) supports ranges of 100-1500 kPa for medium/heavy duty trucks, buses, and construction vehicles.

  • Integrates an 8-bit microcontroller (MCU), pressure sensor, XZ-axis or Z-axis accelerometer and RF transmitter
  • Offers the lowest power consumption and dual-axis accelerometer architecture, enables small module design for lighter weight and space-constrained applications
  • Offers flexibility of software development and accelerated time-to-market
