MFS8601BMBA0ESR2

Power Management - Specialized Overview

The MFS8601BMBA0ESR2 is a fail-safe system basis chip (SBC) from the FS86 family, designed for domain controller applications with ASIL B compliance. It integrates multiple switch-mode power supplies (SMPSs), linear regulators (LDOs), and a boost converter. The device supports up to 60 V DC input voltage and features an HV BUCK with e-fuse protection. It includes low-power OFF mode with 10 µA sleep current, XFAILB-based leader/follower sequencing, and AMUX. Configuration is managed via One Time Programmable (OTP) memory and a 32-bit I²C interface with CRC. EMC optimization includes spread spectrum and slew rate control.
