The FS66 is an automotive, functionally safe
multi-output power supply integrated circuit. It’s focused on powertrain, safety and chassis applications and is the primary companion chip of the
S32S2 microcontroller.
The FS66 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 D safety integrity level.
It is developed in compliance with the ISO 26262 standard and will be qualified according to AEC-Q100 rev H requirements.
Part numbers include: MC33FS6600M0ES, MC33FS6600M0KS, MC33FS6600M1ES, MC33FS6600M1KS, MC33FS6600M2ES, MC33FS6600M2KS.
