Product details
Overview
MFS8416AMBP3ES from NXP Semiconductors is a functionally safe, ASIL B-compliant system basis chip (SBC) designed for automotive radar applications. It integrates a 10 A peak VPRE synchronous buck controller, a 4.5 A BUCK1 core regulator (1.25 V output), a 4.5 A BUCK3 regulator (2.3 V output), a BOOST converter (5.74 V), two LDOs (3.3 V/150 mA and 5.0 V/150 mA), and fail-safe outputs - all in a HVQFN48EP package with wettable flanks.
For engineers reviewing the MFS8416AMBP3ES datasheet, MFS8416AMBP3ES pinout, MFS8416AMBP3ES application, or MFS8416AMBP3ES equivalent, this page delivers verified technical context, safety-critical power sequencing details, OTP-configured regulator settings for radar systems, and validated alternative options aligned to ISO 26262 ASIL B requirements.
Technical Context
The MFS8416AMBP3ES implements dual independent state machines: a main power management state machine handling wake-up, standby, and regulator sequencing, and a dedicated fail-safe state machine managing ABIST, voltage supervision (VCOREMON, VMON1–4), FCCU-based MCU error monitoring, and deep fail-safe auto-retry (x15). Its safety architecture supports full ASIL B partitioning per ISO 26262.
Regulator control uses SPI (32-bit with CRC) for configuration and runtime adjustment, while hardware-level safety features include programmable undervoltage/overvoltage detection (UVTH/OVTH with 15–25 µs delay), thermal shutdown coordination across all SMPS/LDOs, and fail-safe output FS0B (open-drain, active-low) with configurable assertion timing.

Applications
| Radar Sensor Power Management | ADAS Domain Controller Supply |
|---|---|
Use Scenario: Powers 77 GHz corner radar modules requiring low-noise, tightly regulated rails for RF transceivers and DSP cores. IC Role / Device Role / Timing Role: System basis chip providing VPRE (3.3 V), BUCK1 (1.25 V), BUCK3 (2.3 V), and BOOST (5.74 V) with ASIL B fail-safe monitoring. Use Value: Enables single-chip power solution meeting automotive radar EMI limits and functional safety requirements without discrete supervisors. | Use Scenario: Supplies NXP S32R274/S32R294 radar MCUs in centralized ADAS domain controllers with coordinated power-up sequencing. IC Role / Device Role / Timing Role: Integrates core, IO, analog, and boost rails with slot-based sequencing and real-time voltage supervision (VCOREMON, VMON1–4). Use Value: Reduces BOM count by replacing 6+ discrete regulators and supervisors while maintaining ISO 26262 ASIL B compliance. |
| Vision Processing Unit (VPU) Interface | Automotive Gateway with Radar Integration |
Use Scenario: Delivers clean, sequenced power to radar-Vision fusion processors (e.g., S32R45) requiring simultaneous 1.25 V core and 2.3 V interface rails. IC Role / Device Role / Timing Role: Dual SMPS (BUCK1/BUCK3) with independent current limits (4.5 A each) and soft-start (7.81 mV/µs) prevent inrush-induced voltage droop. Use Value: Ensures stable power delivery during simultaneous radar scan and camera frame capture, avoiding timing faults in sensor fusion algorithms. | Use Scenario: Used in gateway ECUs integrating radar data preprocessing with CAN FD and Ethernet communication stacks. IC Role / Device Role / Timing Role: Provides isolated LDO1 (3.3 V) and LDO2 (5.0 V) for CAN PHY and Ethernet PHY interfaces, with independent TSD behavior. Use Value: Prevents cascading failure - LDO2 shutdown during overtemperature does not affect BUCK1/BUCK3, preserving radar processing capability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar system basis chip applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MFS8412AMBP7ES | Same HVQFN48EP package; BUCK1 = 1.25 V/4.5 A, BUCK3 = 2.3 V/4.5 A, but includes PSYNC enabled and phase-shift delay 3 - optimized for dual-FS84 radar synchronization | Targeted for radar systems using NXP S32R274 MCU with dual-SBC redundancy | Select when dual-device synchronization or higher-level MCU integration (S32R274) is required; not drop-in due to PSYNC enable and different ABIST configuration |
| MFS8406AMBP4ES | Same package; VPRE = 3.3 V/10 A, BUCK1 = 1.25 V/2.6 A, BUCK3 disabled, LDO1 = 5.0 V/150 mA - lower BUCK1 current, no BUCK3 | Targeted for camera-based vision systems (mono/stereo) rather than radar | Select for vision-only applications where 2.6 A core supply suffices and BUCK3 is unnecessary; differs in OTP power tree and sequencing slots |
Compared with MFS8416AMBP3ES, MFS8412AMBP7ES adds PSYNC and MCU-specific sequencing for S32R274, while MFS8406AMBP4ES reduces BUCK1 capability and removes BUCK3 - both require OTP revalidation and are not pin-compatible replacements.

FAQ
What is the primary application target for the MFS8416AMBP3ES?
The MFS8416AMBP3ES is specifically targeted for automotive radar systems, as indicated by its ordering information table and OTP configuration - it delivers preprogrammed 3.3 V VPRE, 1.25 V BUCK1, 2.3 V BUCK3, and fail-safe supervision optimized for 77 GHz radar sensor modules and associated domain controllers.
Does the MFS8416AMBP3ES support SPI configuration during operation?
Yes, the MFS8416AMBP3ES supports full runtime SPI configuration via its 32-bit interface with CRC protection. While OTP defines baseline regulator voltages and sequencing, SPI enables dynamic adjustment of soft-start rates, fault thresholds, and power-state transitions - critical for radar system calibration and adaptive power management.
What safety certifications apply to the MFS8416AMBP3ES?
The MFS8416AMBP3ES complies with ISO 26262 up to ASIL B and is qualified per AEC-Q100 Grade 1 (−40 °C to +125 °C). It includes dual ABIST, FCCU-based MCU monitoring, programmable voltage supervision (VCOREMON, VMON1–4), and deep fail-safe auto-retry - all verified for automotive radar safety integrity.
How is thermal performance managed on the MFS8416AMBP3ES?
The MFS8416AMBP3ES uses an HVQFN48EP package with exposed thermal pad (EP) connected to GND, achieving RθJB = 10 °C/W on a 2s6p board. Thermal shutdown (TSD) is coordinated across all regulators - BUCK1, BUCK3, BOOST, and LDOs shut down independently based on OTP-configured behavior, preventing thermal runaway in radar ECU enclosures.
Can the MFS8416AMBP3ES be used in non-radar automotive applications?
While the MFS8416AMBP3ES is optimized for radar, its ASIL B compliance, wide input range (4.9–40 V), and flexible OTP configuration allow use in other safety-critical domains like vision ECUs or gateway systems - provided the specific OTP settings (e.g., 1.25 V BUCK1, 2.3 V BUCK3) align with the target application's power requirements.
