Melexis IC cuts TPMS size and reduces power consumption

Melexis MLX91804 tyre pressure monitoring IC

Melexis has introduced its third generation IC for tyre pressure monitoring systems (TPMS). The MLX91804 comes in a 14-pin DFN type lead-less package and is claimed to have a 60 per cent smaller footprint and draw three times lower sleep mode current than other TPMS ICs.

It incorporates a microcontroller and mems-based pressure sensing element, as well as a 315 and 433MHz wireless transmitter supporting data rates up to 150kbit/s and 125kHz receiver for communications with the vehicle’s ECU.
