Product details
Overview
MFS8613BMBA0ESR2 from NXP Semiconductors is a fail-safe system basis chip (SBC) designed for 24 V battery network automotive domain controllers, integrating a 15 A high-voltage buck controller (VPRE), 1 A boost converter (BOOST), 2.5 A synchronous buck (BUCK), two 400 mA LDOs, and ten ±1 % accurate voltage monitors. It supports ASIL B safety compliance, I²C configuration, and cascaded power sequencing via XFAILB for radar and ADAS applications.
For engineers reviewing the MFS8613BMBA0ESR2 datasheet, MFS8613BMBA0ESR2 pinout, MFS8613BMBA0ESR2 application, or MFS8613BMBA0ESR2 equivalent, this page delivers verified functional safety architecture, regulator output configurations, fail-safe output behavior (PGOOD/RSTB/FS0B), thermal performance (RθJA = 23 °C/W), and OTP-programmable features specific to the MFS8613 variant with A0 silicon revision and wettable flank QFN48 package.
Technical Context
The MFS8613BMBA0ESR2 implements a leader/follower power-up sequencing architecture synchronized through the XFAILB pin, enabling coordinated startup across cascaded SBCs in domain controller platforms. Its fail-safe state machine independently supervises ten voltage rails-including external PMIC outputs-using dedicated analog monitoring paths with ±1 % accuracy and built-in ABIST/LBIST.
It integrates three switching regulators (VPRE, BOOST, BUCK) with EMC-optimized control: spread spectrum, slew rate tuning, and manual frequency adjustment. The device uses a 32-bit I²C interface with 8-bit CRC for configuration and watchdog monitoring, supporting both simple and challenger watchdog modes per ASIL B requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar fail-safe SBC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MFS8613BMDA0ES | Same silicon (A0), identical regulator specs and pinout, but qualified for ASIL D instead of ASIL B | Required where full ASIL D decomposition is mandated; higher safety case coverage via challenger watchdog and extended ABIST | Select MFS8613BMDA0ES when system-level ASIL D allocation requires certified diagnostic coverage beyond ASIL B scope |
| MFS8633BMBA0ES | 12 V battery network variant (36 V max input); same regulator topology and feature set but lower VSUP rating | Designed for passenger car 12 V architectures; not rated for 60 V transients present in 24 V commercial vehicles | Choose MFS8633BMBA0ES only for automotive 12 V applications where 36 V absolute max input suffices |
Compared with MFS8613BMBA0ESR2, MFS8613BMDA0ES provides higher safety certification without electrical or mechanical change, while MFS8633BMBA0ES reduces input voltage capability for cost-optimized 12 V use cases-neither is pin-to-pin compatible due to differing qualification grades and voltage ratings.

FAQ
What safety standard compliance does the MFS8613BMBA0ESR2 support?
The MFS8613BMBA0ESR2 is developed in compliance with ISO 26262 and qualified per AEC-Q100 Grade 1 (−40 °C to 125 °C). It supports ASIL B system integration with dedicated watchdog monitoring (FCCU1/FCCU2), ERRMON input for external IC failure detection, and latent fault detection on PGOOD, RSTB, and FS0B outputs. Full ASIL D capability requires the MFS8613BMDA0ES variant.
Does the MFS8613BMBA0ESR2 include integrated MOSFETs for all its regulators?
No. The MFS8613BMBA0ESR2 integrates MOSFETs only for the BOOST and BUCK regulators. The VPRE buck controller requires external high-side and low-side FETs-pins PRE_GHS, PRE_GLS, PRE_SW, and PRE_BOOT are provided for that purpose. This architecture enables the 15 A output capability and e-fuse protection functionality unique to the VPRE stage.
How many voltage rails can the MFS8613BMBA0ESR2 monitor, and what is the accuracy?
The MFS8613BMBA0ESR2 supports monitoring of up to ten voltage rails with ±1 % accuracy across its VMON0_I2C to VMON9_RES inputs. VMON0–VMON3 accept DAC-based inputs for precision internal rail sensing, while VMON4–VMON9 use resistor-bridge configurations for external rail monitoring-including those from non-NXP PMICs or discrete regulators.
What is the function of the XFAILB pin on the MFS8613BMBA0ESR2?
The XFAILB pin enables power-up/down sequencing synchronization between multiple FS86 devices in a cascaded architecture. When configured as leader, it drives timing; as follower, it aligns its internal power state machine to the leader's XFAILB signal-ensuring deterministic, glitch-free startup across complex domain controllers with multiple SBCs and PMICs.
Can the MFS8613BMBA0ESR2 operate in a 12 V automotive battery system?
No. The MFS8613BMBA0ESR2 is specifically designed for 24 V battery networks with a 60 V maximum input rating. For 12 V systems (36 V max), the MFS8633BMBA0ES variant is specified. Using MFS8613BMBA0ESR2 in a 12 V application is electrically permissible but violates qualification scope and may trigger unnecessary overvoltage protection or complicate thermal design due to unused headroom.
