Product Overview
The MLX90824 is a highly integrated, PCB-less absolute pressure sensor designed for automotive applications. It measures pressure spans from 1 to 4 bar and delivers a digital output via the SENT protocol. The device features MEMS pressure sensing, an interface IC, and passive components, offering excellent EMC performance and high accuracy due to its DSP-based signal interface. It is factory calibrated and programmable for customized calibration curves, with flexible NTC input for external temperature measurement. The sensor is qualified according to AEC-Q100 and AEC-Q103-002 standards and supports ASIL B development.
