PCB-less absolute MEMS pressure sensor IC (SENT) - MLX90824

Product description

The MLX90824 is a packaged PCB-less, factory calibrated, absolute pressure sensor measuring spans from 1 to 4 bars. It delivers a digital output signal using the SENT protocol.

The MLX90824 consists of a MEMS pressure sensor element, an interface chip (CMOS technology) and passive components. The optimized solution exhibits excellent EMC performance. The DSP based signal interface provides outstanding initial accuracy. A smart package and die assembly concept enable high output stability over life, even in stringent automotive temperature and stress conditions.

The MLX90824 is ASIL compliant and support safety critical applications. It has been developed as an ASIL B SEooC (Safety Element out of Context) as per ISO 26262.

An accuracy of +/-0.5 %FS (full scale) is maintained over the course of the sensor’s working lifespan. This accuracy is not impacted by the sensor integration thanks to the PCB-less packaging.

A pre-calibrated NTC thermistor (negative temperature coefficient) input is available for the MLX90824. This allows customers to interface their NTC through the pressure sensor without end of line calibration.

The MLX90824 is factory calibrated or fully programmable through the connector with the PTC-04 (PTC-04 DB-HALL06) for customized calibration curves. Contact your local representative for more information.
