Product details
Overview
MFS8416AMBP5ES from NXP Semiconductors is a functionally safe, ASIL B-compliant system basis chip (SBC) designed for automotive gateway applications with the MPC5748G MCU. It integrates a 3.3 V VPRE synchronous buck controller (10 A peak), 1.2 V BUCK1 core regulator (4.5 A), 1.8 V BUCK3 (4.5 A), 5.0 V BOOST (1.5 A), and dual LDOs (1.8 V/400 mA and 3.3 V/400 mA), all synchronized via SPI and FSYNC for EMC-optimized radar/ADAS power delivery.
For engineers reviewing the MFS8416AMBP5ES datasheet, MFS8416AMBP5ES pinout, MFS8416AMBP5ES application, or MFS8416AMBP5ES equivalent, this device delivers fail-safe power sequencing, deep fail-safe auto-retry (x15), integrated voltage supervision (VCOREMON, VMON1–4), and SPI-controlled configuration - critical for MPC5748G-based gateways requiring ISO 26262 compliance and AEC-Q100 Grade 1 operation.
Technical Context
The MFS8416AMBP5ES implements two 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, FCCU monitoring, and fault response with deep fail-safe (DFS) recovery. Its OTP-programmed configuration fixes VPRE at 3.3 V with Force PWM mode, BUCK1 at 1.2 V, BUCK3 at 1.8 V, LDO1 at 1.8 V/400 mA, and LDO2 at 3.3 V/400 mA - all assigned to specific power-up slots (Slot 0–3) for deterministic sequencing.
It supports external frequency synchronization (FIN/FOUT), PSYNC for multi-device coordination, and safety-critical monitoring including VCOREMON (1.2 V threshold), VMON1–4 with configurable OV/UV thresholds (e.g., VMON1: 109% OVTH, 95.5% UVTH), and fail-safe outputs (FS0B, PGOOD, RSTB). All regulators feature thermal shutdown (TSD) and programmable soft-start (DVS).

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, BUCK3 = 2.3 V, LDO1 = 3.3 V/150 mA, no LDO2; PLL enabled; VMON3/4 enabled | Targeted for radar with S32R274 MCU; lower LDO current, different voltage setpoints, and extended monitoring scope | Select when needing S32R274 compatibility, reduced LDO load, or additional VMON channels - not drop-in for MPC5748G gateway |
| MFS8406AMBP4ES | Same package; BUCK1 = 1.25 V, no BUCK3, LDO1 = 5.0 V/150 mA, LDO2 absent; VPRE = 3.3 V, BOOST = 5.74 V | Optimized for camera modules; lacks BUCK3 and second LDO, higher BOOST voltage for image sensor bias | Choose for camera ECU designs requiring 5.74 V BOOST and simplified rail count - incompatible with MPC5748G's dual-LDO requirement |
Compared with MFS8416AMBP5ES, MFS8412AMBP7ES offers expanded voltage monitoring but reduced LDO capability, while MFS8406AMBP4ES sacrifices BUCK3 and LDO2 for camera-specific BOOST voltage - neither matches the MPC5748G gateway's exact 1.2 V/1.8 V/1.8 V/3.3 V/5.0 V rail set and 400 mA LDO current.

FAQ
What is the primary application target for the MFS8416AMBP5ES?
The MFS8416AMBP5ES is specifically configured for automotive gateway systems using the NXP MPC5748G MCU. Its OTP settings - including 1.2 V BUCK1, 1.8 V BUCK3, 1.8 V/400 mA LDO1, and 3.3 V/400 mA LDO2 - match the power architecture of MPC5748G-based designs, with sequencing slots and fail-safe monitoring optimized for central vehicle networking.
Does the MFS8416AMBP5ES support external frequency synchronization?
Yes, the MFS8416AMBP5ES supports external frequency synchronization via dedicated FIN (pin 18) and FOUT (pin 21) pins. This allows alignment of its 2.22 MHz SMPS switching with other system clocks or external PMICs, reducing electromagnetic interference in dense automotive PCB layouts - a key feature confirmed in the device's electrical characteristics and block diagram.
What safety certifications does the MFS8416AMBP5ES hold?
The MFS8416AMBP5ES complies with ISO 26262 up to ASIL B and is qualified per AEC-Q100 Grade 1 (−40 °C to +125 °C ambient). It includes integrated safety mechanisms such as ABIST, FCCU monitoring, deep fail-safe auto-retry (x15), and configurable voltage supervision (VCOREMON, VMON1–4), all verified in the official product data sheet Rev. 4.0.
How is power sequencing controlled on the MFS8416AMBP5ES?
Power sequencing on the MFS8416AMBP5ES is controlled by an eight-slot hardware sequencer programmed via OTP. For example, BUCK1 starts/stops in Slot 1, LDO1 in Slot 2, and LDO2 in Slot 1 - enabling deterministic, glitch-free power-up/down timing without MCU intervention. This is explicitly defined in Table 3 of the datasheet for the MFS8416AMBP5ES flavor.
What are the key differences between MFS8416AMBP5ES and MFS8412AMBP7ES?
The MFS8416AMBP5ES features 1.2 V BUCK1, 1.8 V BUCK3, 1.8 V/400 mA LDO1, and 3.3 V/400 mA LDO2 for MPC5748G gateways, while MFS8412AMBP7ES provides 1.25 V BUCK1, 2.3 V BUCK3, 3.3 V/150 mA LDO1, and no LDO2 for S32R274 radar systems. Their VMON enablement, PLL status, and fail-safe configurations also differ - making them application-specific, not interchangeable.
