Product details
Overview
MFS8610BMBA0ESR2 from NXP Semiconductors is a fail-safe system basis chip (SBC) designed for automotive domain controllers, integrating a 15 A high-voltage synchronous buck controller (VPRE), 1 A boost converter (BOOST), 2.5 A low-voltage buck (BUCK), two 400 mA LDOs (LDO1/LDO2), and ten ±1 % accurate voltage monitors. It supports 24 V battery networks (60 V max), operates from −40 °C to 125 °C, and delivers ASIL B safety compliance per ISO 26262 for ADAS and radar power management.
For engineers reviewing the MFS8610BMBA0ESR2 datasheet, MFS8610BMBA0ESR2 pinout, MFS8610BMBA0ESR2 application, or MFS8610BMBA0ESR2 equivalent, this device serves as a scalable, software-compatible upgrade to FS84/85 with synchronized power sequencing, I²C-based configuration, and fail-safe outputs (PGOOD, RSTB, FS0B) critical for safety-critical vehicle subsystems.
Technical Context
The MFS8610BMBA0ESR2 implements a leader/follower architecture via XFAILB for cascaded SBC synchronization, enabling coordinated power-up sequencing across multiple PMICs in domain controller platforms. Its BYLink-compatible design allows distributed system-level safety coordination without external timing controllers.
It integrates dual watchdog monitoring (simple and challenger modes), dedicated MCU failure detection via FCCU1/FCCU2 inputs, and ERRMON for external IC fault reporting. All ten VMON inputs support configurable accuracy targeting ±1 %, covering both internal rails (e.g., VCORE, VPRE) and external PMIC outputs via resistor-divider or DAC-based sensing.
Key Specifications
