ZSSC4132CE4W

The ZSSC4132 automotive sensor signal conditioner delivers high accuracy, flexibility and excellent cost efficiency with integrated LIN, best-in-class analogue front end and reduced bill of materials. It can be configured for nearly all resistive bridge sensors. This flexibility, combined with leading performance levels, an integrated LIN PHY, small package footprint and AEC-Q100 grade 0 qualifications, makes the SSC ideally suited for small automotive sensor modules with limited space, tight budget and end-of-line (EOL) calibration requirements. Its digital calibration significantly reduces noise sensitivity and delivers high accuracy for pressure and temperature readings. Typical application include HVAC systems in PHEV and FCEV (coolant pressure and temperature), seat and door module systems, supporting all HVAC coolant media including CO2 and fluid level sensing.
