Product details
Overview
MPF7100BVBA3ES from NXP Semiconductors is a 7-channel automotive-grade PMIC designed specifically for i.MX8DX and i.MX8DXP processors, delivering five high-efficiency buck converters (0.4–1.8 V @ 2.5 A each), two 400 mA LDOs, and dual RTC supplies (VSNVS1/VSNVS2). It integrates ASIL B safety monitoring, one-time programmable configuration memory, and supports LPDDR4 memory power sequencing in infotainment systems.
For engineers reviewing the MPF7100BVBA3ES datasheet, MPF7100BVBA3ES pinout, MPF7100BVBA3ES application, or MPF7100BVBA3ES equivalent, key selection considerations include its AEC-Q100 Grade 2 qualification (−40 °C to +105 °C), 3.4 MHz I²C interface, HVQFN48 package with wettable flanks, and OTP-programmed startup sequence for i.MX8DXP/LPDDR4 systems.
Technical Context
The MPF7100BVBA3ES implements a deterministic state machine with ASIL B–compliant self-test (ABIST, CRC-verified mirror registers, thermal/fault monitoring) and fail-safe transition logic triggered by FSOB assertion. Its regulator control supports dynamic voltage scaling on SW1–SW4, VTT termination on SW3, and quad-phase configuration up to 10 A via phase interleaving.
Power tree management includes hardware-configurable startup sequencing stored in OTP, real-time I²C reconfiguration of output voltages and timing, and analog multiplexer-based system diagnostics. Safety features are enabled only in ASIL B variants (e.g., MPF7100BVBA3ES), with dedicated fault counters (FS_CNT), secure I²C write enable, and fail-safe state locking absent in QM-grade parts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | VIN = 2.7 V to 5.5 V - powers entire PMIC from single automotive rail; UVLO threshold at 2.7 V ensures reliable startup under cold-crank conditions. |
| Buck Output Accuracy | ±2 % over temperature - guarantees stable core voltage for i.MX8DXP CPU clusters during dynamic load transients. |
| LDO Output Accuracy | ±3 % - maintains tight regulation for SD card (LDO2) and analog peripherals (LDO1) without external feedback compensation. |
| I²C Interface Speed | Up to 3.4 MHz - enables rapid runtime voltage adjustment across all 7 channels during processor DVFS transitions. |
| Thermal Rating | Ambient: −40 °C to +105 °C (AEC-Q100 Grade 2); Junction max 150 °C - validated for under-dash automotive environments with forced-air or passive PCB cooling. |
| Safety Certification | ASIL B compliant per ISO 26262 - includes independent voltage monitors, ABIST, watchdog timer with configurable timeout, and fail-safe output (FSOB) for system-level fault containment. |
| OTP Configuration | One-time programmable memory stores boot voltage, sequencing order, and safety thresholds - eliminates external resistors and reduces BOM count by ≥6 components. |
Pinout & Package
HVQFN48 (7 mm × 7 mm, 0.5 mm pitch, thermally enhanced with wettable flanks and exposed EPAD). Package meets AEC-Q100 mechanical stress requirements and supports automated optical inspection (AOI) via dimple flanks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW1FB–SW5FB (Pins 6,7,12,30,31) | Buck feedback inputs | Enable closed-loop regulation; support external resistor dividers for precise output voltage setting (e.g., SW1FB sets 1.0 V core rail for i.MX8DXP). |
| VSNVS1 / VSNVS2 (Pins 22,23) | RTC LDO outputs | Provide always-on 1.8/3.0 V (VSNVS1) and 0.8/0.9/1.8 V (VSNVS2) rails for real-time clock and secure subsystems during deep sleep. |
| FSOB (Pin 36) | Fail-safe output | Open-drain signal asserted LOW during critical faults (thermal shutdown, register CRC failure, watchdog timeout) to trigger MCU-safe state entry. |
| WDI / RESETBMCU (Pins 1,35) | Watchdog input / MCU reset output | WDI accepts MCU watchdog pulses; RESETBMCU releases after successful power-up sequence to initialize i.MX8DXP boot ROM. |
| VDDIO (Pin 9) | I/O supply | Accepts 1.6–3.3 V - decouples I²C/SCL/SDA logic from core analog rails, enabling interoperability with 1.8 V or 3.3 V host controllers. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL B functional safety architecture | Includes ABIST, mirrored register CRC, programmable fault counters, and FSOB-driven system lockdown - satisfies ISO 26262 requirements for automotive infotainment ECUs. |
| OTP-configured power sequencing | Eliminates need for external sequencer IC or FPGA logic; startup order, delay times, and enable dependencies are固化 in silicon for repeatable, layout-independent boot behavior. |
| Dual-phase and quad-phase buck capability | SW1–SW4 can be combined into 2-, 3-, or 4-phase configurations (up to 10 A total) - supports high-current CPU cores while minimizing output ripple and EMI. |
| VTT termination on SW3 | Configurable as DDR VTT supply (0.4–1.8 V) with current-sink/source capability - directly powers LPDDR4 DQ/DQS terminations without external circuitry. |
| Analog multiplexer (AMUX) diagnostics | Routes internal voltage monitors (VDDIO, V1P5A, V1P5D, etc.) to single pin for oscilloscope or ADC sampling - enables real-time health monitoring without additional test points. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPF7100BVMA3ES | QM-grade variant (no ASIL B safety features: no ABIST, no FSOB, no CRC-protected registers) | Targeted at industrial or non-safety-critical automotive modules where functional safety certification is not required | Select when cost sensitivity outweighs ISO 26262 compliance needs; identical pinout and electrical specs except safety logic |
| PF8100A0ES | Successor PMIC with higher integration (integrated fuel gauge, enhanced thermal sensing, 4.2 MHz I²C), same HVQFN48 package | Designed for next-gen i.MX9x platforms; supports newer memory standards and advanced power states not implemented in PF7100 | Choose for new designs targeting i.MX9; not drop-in compatible due to different OTP structure and register map |
Compared with MPF7100BVBA3ES, MPF7100BVMA3ES removes safety-critical firmware and hardware blocks to reduce cost, while PF8100A0ES extends functionality for future i.MX platforms but requires full hardware and firmware redesign - MPF7100BVBA3ES remains optimal for production i.MX8DXP/LPDDR4 systems requiring certified ASIL B operation.

FAQ
What is the operating temperature range for MPF7100BVBA3ES?
MPF7100BVBA3ES is qualified to AEC-Q100 Grade 2, supporting ambient temperatures from −40 °C to +105 °C. This range is validated for under-dash automotive environments and includes derating guidance up to 150 °C junction temperature. The device uses internal thermal monitoring with automatic shutdown at TJ > 150 °C to protect itself and downstream circuits.
Does MPF7100BVBA3ES support LPDDR4 memory power sequencing?
Yes, MPF7100BVBA3ES is specifically configured for i.MX8DXP and LPDDR4 memory in the MPF7100BVBA3ES variant. Its OTP programming defines precise startup timing for VDDQ (via SW4), VTT (via SW3), and VDDIO (via LDO2), meeting JEDEC JESD209-4 timing requirements including tDQSS, tDQSCK, and VTT ramp rates.
How does the ASIL B safety monitoring work in MPF7100BVBA3ES?
MPF7100BVBA3ES implements ASIL B monitoring through independent voltage comparators, ABIST for analog monitor validation, CRC-protected mirror registers, and a dedicated fail-safe output (FSOB). Upon detecting critical faults - such as register corruption, thermal violation, or watchdog timeout - FSOB asserts LOW to signal the host MCU to enter a safe state, satisfying ISO 26262 fault response requirements.
Can MPF7100BVBA3ES be reconfigured after power-up?
Yes, MPF7100BVBA3ES supports full runtime reconfiguration via its 3.4 MHz I²C interface. Engineers can adjust output voltages (e.g., SW1 from 1.0 V to 1.1 V), modify soft-start times, enable/disable regulators, and update fault thresholds without resetting the device - enabling dynamic power management for i.MX8DXP DVFS states.
What package type and pin count does MPF7100BVBA3ES use?
MPF7100BVBA3ES uses an HVQFN48 package: 7 mm × 7 mm, 0.5 mm pitch, with 48 signal terminals plus an exposed thermal pad (EPAD).
