Single-package tyre pressure monitoring system

28 November 2007 Analogue, Mixed Signal, LSI

Freescale Semiconductor has introduced a tyre pressure monitoring system (TPMS) containing a capacitive pressure sensor for ultra-low power consumption and precise sensing.

The MPXY8300 system-in-package device provides a highly integrated, cost-effective solution that combines an advanced pressure sensor with an 8-bit microcontroller (MCU), 2-axis accelerometer and radio frequency (RF) capability.

This solution is designed to help drivers maintain proper tyre pressures by instantly notifying them when any individual tyre (including the spare) is not at the optimal pressure level. Engineered for wheel-mounted applications, the highly integrated MPXY8300 system helps automotive engineers reduce development cycle time, component count and system cost by combining the necessary digital, analog and sensor functions of a TPMS in a single, compact package.

The MPXY8300 offers precise, realtime tyre pressure measurement using direct monitoring at each wheel. Additionally, the single-package solution has an integrated accelerometer for motion detection. The system can be programmed to transmit measurements at certain tyre rotation speeds and even when the tyres are not rotating at all.
