DESCRIPTION

· The MLX90825 is a relative pressure sensor with a digital SENT output, designed for automotive applications.

FEATURES

· Offers +/-0.5% full scale lifetime accuracy.

· Features a digital SENT output and can output linear temperature measured by an external NTC thermistor.

· Supports a wide range of NTC characteristics without calibration.

· Integrated MEMS, interface, and passive components in a single package, validated to leading OEM EMC standards.

· Operates in a temperature range from -40°C to 160°C, with short durations up to 170°C.

· Resistant to harsh media including halogens and acids.

· Qualified according to AEC-Q100 and AEC-Q103-002 standards.

· Includes configurable diagnostic features such as output out of range, over voltage, and under voltage.

· Factory calibrated and fully programmable via the PTC04 programming tool for customized calibration curves.

· Supports extended over (+40V) and reverse (-40V) voltage capabilities for supply and output.

· Designed for easy use with a PCB-less package featuring ridges for glued pressure seals.

· ASIL compliant, developed as an ASIL B SEooC per ISO 26262.

APPLICATIONS

· Suitable for automotive applications with relative pressure spans from 0.1 bar to 1.5 bar.

· Ideal for use as a fuel vapor pressure sensor, crankcase ventilation pressure sensor, and pressure sensor for filter monitoring.
