MFS2401AVMAFESR2

Power Management - Specialized Overview

The MFS2401AVMAFESR2 is an automotive System Basis Chip (SBC) from NXP, designed for high-reliability applications. It integrates two high-voltage DC-DC buck converters: a controller with external FETs supporting up to 15A load and a regulator with internal FETs delivering 3A. The device features ASIL B functional safety compliance, including independent voltage monitors, a windowed watchdog timer, and built-in self-test capabilities. It operates within a temperature range of -40°C to 150°C TJ and offers programmable supplies via One Time Programmable memory.
