Product details
Overview
MFS8613BMDA0ES from NXP Semiconductors is a fail-safe system basis chip (SBC) designed for automotive domain controllers requiring ASIL D compliance, integrated power management, and functional safety monitoring. It delivers 15 A VPRE buck regulation, 2.5 A BUCK, 1 A BOOST, dual 400 mA LDOs, ±1 % voltage monitoring across 10 inputs, and operates in 24 V battery networks up to 60 V input.
For engineers reviewing the MFS8613BMDA0ES datasheet, MFS8613BMDA0ES pinout, MFS8613BMDA0ES application, or MFS8613BMDA0ES equivalent, this page provides verified technical context, safety-critical specifications, I²C-configurable power sequencing, fail-safe outputs (PGOOD/RSTB/FS0B), and BYLink synchronization capability for cascaded SBC systems.
Technical Context
The MFS8613BMDA0ES implements a hierarchical safety architecture with independent analog voltage supervision circuitry, logical and analog built-in self-test (LBIST/ABIST), and dedicated MCU failure monitoring via FCCU1/FCCU2 PWM inputs. Its fail-safe state machine manages PGOOD, RSTB, and FS0B outputs with latent fault detection.
It supports leader/follower power-up sequencing through XFAILB, offers 10 ms configurable RSTB release delay for MCU compliance, and enables synchronized operation across multiple PMICs via BYLink-using FIN/FOUT for frequency coordination and AMUX for multiplexed analog monitoring routed to MCU ADC.

Equivalent & Alternatives
The following parts are listed as comparable options for similar fail-safe SBC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MFS8613BMBA0ES | Same silicon (A1), identical electrical specs, but rated for ASIL B only (not D) | Lacks challenger watchdog and full ASIL D FMEDA certification; suitable for ASIL B domain controllers | Select when ASIL D is not required and cost optimization is prioritized |
| MFS8633BMDA0ES | 36 V max input (for 12 V networks); same ASIL D rating, OTP, and BYLink capability | Designed for passenger car 12 V battery systems-not rated for 60 V transients or 24 V commercial vehicle use | Choose for ASIL D applications in automotive 12 V networks where lower input voltage suffices |
Compared with MFS8613BMDA0ES, MFS8613BMBA0ES reduces safety certification scope (ASIL B only) while retaining identical power capability, whereas MFS8633BMDA0ES maintains ASIL D compliance but limits input voltage to 36 V-making it unsuitable for 24 V battery networks requiring 60 V tolerance.

FAQ
What is the maximum input voltage supported by the MFS8613BMDA0ES?
The MFS8613BMDA0ES supports a maximum input voltage of 60 V DC on VSUP1 and VSUP2 pins, making it suitable for 24 V battery network applications in trucks, buses, and off-highway vehicles. This rating complies with AEC-Q100 Grade 1 and includes transient protection design for automotive environments. The device also operates down to 4.5 V battery voltage when VPRE is configured to 3.3 V.
Does the MFS8613BMDA0ES include integrated MOSFETs for all its regulators?
No-the MFS8613BMDA0ES integrates MOSFETs only for the BOOST and BUCK regulators. The VPRE buck controller is external-FET-based, requiring high-side and low-side external MOSFETs driven by PRE_GHS and PRE_GLS outputs. This architecture enables 15 A output capability and e-fuse protection, while BOOST (1 A) and BUCK (2.5 A) use fully integrated synchronous FETs for compactness and efficiency.
How many voltage monitoring inputs does the MFS8613BMDA0ES support, and what is their accuracy?
The MFS8613BMDA0ES supports exactly 10 voltage monitoring inputs (VMON0–VMON9), with a target accuracy of ±1 % across temperature and supply conditions. Inputs include mixed types: VMON0_I2C is a dedicated I²C-supplied reference; VMON1–VMON3 accept DAC outputs; VMON4_RINT uses internal resistors; and VMON5–VMON9_RES use external resistor bridges-enabling flexible monitoring of both internal rails and external QM supplies.
What safety certifications apply to the MFS8613BMDA0ES?
The MFS8613BMDA0ES is developed in compliance with ISO 26262 up to ASIL D and qualified per AEC-Q100 Grade 1 (−40 °C to 125 °C). It includes LBIST/ABIST, challenger watchdog, dedicated ERRMON and FCCU monitoring inputs, and safety outputs (PGOOD, RSTB, FS0B) with latent fault detection-fully documented in NXP's FS8600_SDS Rev. 3.0 and supporting FMEDA reports.
Can the MFS8613BMDA0ES be used in 12 V automotive battery networks?
No-the MFS8613BMDA0ES is specifically designed for 24 V battery networks with 60 V maximum input rating. For 12 V networks (36 V max), NXP specifies MFS8633BMDA0ES as the ASIL D-compliant alternative. Using MFS8613BMDA0ES in a 12 V system is electrically possible but violates qualification scope, voids AEC-Q100 compliance claims, and forfeits warranty and safety certification validity.
