Relative pressure sensor IC for EVAP systems in ICE or hybrid vehicles

Product

The automotive qualified relative pressure sensor is a system-in-package IC solution for the reliable measurement of fuel vapor pressure as low as 50 mbar and up to 700 mbar. This makes the MLX90821 suitable for EVAP (evaporation) systems designed for internal combustion engine (ICE) or hybrid vehicles.
