The MLX90821 is a packaged and factory calibrated automotive relative pressure sensor IC with an analog and a SENT output that can be used in applications demanding very low pressures from 50 mbar up to 700 mbar in automotive harsh media applications such as fuel vapor.
The MLX90821 is the ideal solution for measuring very low pressures in applications requiring extended
mission profiles when high robustness is needed.
The same product can be used at 700 mbar to cope with the fuel vapor build-up in hybrid cars as 50 mbar, the classic range for fuel vapor in non-electrified powertrains.
