FS84

Roll over image to zoom in

The FS84 is an automotive, functionally safe multi-output power supply integrated circuit. It’s focused on ADAS sensor (camera, radar, Lidar) applications and is the primary companion chip of the S32 microcontroller.

The FS84 includes multiple switch mode and linear voltage regulators, enhanced safety features with fail-safe outputs. This makes it a full part of a safety-oriented system up to ASIL B safety integrity level.

It is part of a complete family of devices offering scalability in power and safety FS84 and FS85, pin to pin and software compatible. It is developed in compliance with the ISO 26262 standard and is qualified according to AEC-Q100 requirements.
