MC33FS6525NAE

MC33FS6525NAE is a safety power system basis chip with CAN FD and LIN transceivers. It is a multi-output, power supply, integrated circuit, including CAN Flexible Data (FD) and/or LIN transceivers, dedicated to the automotive market. Multiple switching and linear voltage regulators, including low-power mode (32μA) are available with various wake-up capabilities. An advanced power management scheme is implemented to maintain high efficiency over a wide range of input voltages (down to 2.7V) and output current ranges (up to 2.2A). It includes configurable fail-safe/fail silent safety behavior and features, with two fail-safe outputs, becoming a full part of a safety oriented system partitioning, to reach a high integrity safety level (up to ASIL B). The built-in CAN FD interface fulfills the ISO 11898-2 and -5 standards. The LIN interface fulfills LIN protocol specifications 2.0, 2.1, 2.2, and SAE J2602-2.
