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 features a digital SENT output. The sensor combines a MEMS pressure element, an interface IC, and passive components in a single package, offering excellent EMC performance and high accuracy due to its DSP-based signal interface. It supports flexible NTC thermistor input for linear temperature output and is factory calibrated and programmable for customized calibration curves. The device is qualified according to AEC-Q100 and AEC-Q103-002 standards and is developed as an ASIL B SEooC.
