Product details
Overview
MPF7100BVMA3ESR2 from NXP Semiconductors is a 7-channel automotive-grade PMIC designed for i.MX8DX and i.MX8DXP processors, featuring five high-efficiency buck converters (0.4–1.8 V @ 2.5 A), two 400 mA LDOs, one-time programmable configuration memory, and ASIL B–capable safety monitoring. It powers processor cores, LPDDR4 memory, and peripherals in infotainment and telematics systems.
For engineers reviewing the MPF7100BVMA3ESR2 datasheet, MPF7100BVMA3ESR2 pinout, MPF7100BVMA3ESR2 application, or MPF7100BVMA3ESR2 equivalent, this QM-grade variant supports i.MX8DXP/DX with LPDDR4 memory, offers 3.4 MHz I²C programmability, and delivers configurable power sequencing without external resistive networks.
Technical Context
The MPF7100BVMA3ESR2 implements a deterministic state machine with OTP-configured startup sequence, dual-phase and quad-phase buck regulator configurations (up to 10 A total), and VTT termination on SW3 for DDR interface compliance. Its safety architecture includes thermal shutdown, independent voltage monitors, and ABIST diagnostics - though ASIL B features are disabled per QM grade.
It operates across −40 °C to +105 °C (AEC-Q100 Grade 2), accepts 2.7–5.5 V input, and integrates analog/digital ground separation, spread-spectrum switching, and programmable soft-start/soft-stop timing for EMI control and system reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 2.7 V to 5.5 V - supports wide-input automotive battery and DC-DC pre-regulator outputs. |
| Buck Output Range (SW1–SW4) | 0.4 V to 1.8 V in 6.25 mV steps - enables precise core voltage scaling for i.MX8DXP/DX CPU and GPU domains. |
| Buck Current Rating | 2.5 A per buck channel - sufficient for high-performance processor cores and LPDDR4 VDDQ/VTT rails. |
| LDO Output Range | LDO1/LDO2: 0.8 V to 5.0 V @ 400 mA - powers I/O, SD card, and auxiliary peripherals with load-switch option. |
| I²C Interface Speed | Up to 3.4 MHz - enables fast runtime reconfiguration of regulators and fault registers during dynamic power states. |
| OTP Memory | One-time programmable storage - holds startup voltages, sequencing order, and safety thresholds, eliminating external resistor networks. |
| Ambient Temp Range | −40 °C to +105 °C - qualified per AEC-Q100 Grade 2 for under-hood and dashboard-mounted automotive electronics. |
Pinout & Package
MPF7100BVMA3ESR2 uses a 48-pin HVQFN48 package (7 mm × 7 mm × 0.85 mm, 0.5 mm pitch) with exposed thermal pad (EPAD) connected to GND for enhanced thermal dissipation in automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| VSNVS1/VSNVS2 (Pins 22, 21) | RTC backup supplies | Provide 1.8/3.0/3.3 V or 0.8/0.9/1.8 V @ 10 mA for real-time clock retention during deep sleep. |
| PGOOD/INTB/FSOB (Pins 38, 37, 36) | Status and safety outputs | Open-drain signals indicate power-good status, interrupt events, and fail-safe assertion (QM mode: FSOB functional but not ASIL-B locked). |
| SCL/SDA (Pins 11, 10) | I²C interface | Support up to 3.4 MHz operation; used for runtime configuration, monitoring, and register readback. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPF7100BVBA3ES | ASIL B–qualified; includes full ABIST, FSOB lock-down, and secure I²C write capability. | Required for safety-critical ADAS modules where ISO 26262 ASIL B compliance is mandated. | Select MPF7100BVBA3ES when functional safety certification is required; MPF7100BVMA3ESR2 suffices for QM systems with internal safety handling. |
| PF8100A0ES | Dual-core PMIC with integrated USB-C PD controller; supports higher VIN (up to 22 V); no OTP memory. | Targets USB-C powered automotive accessories requiring direct battery input and Type-C negotiation. | Choose PF8100A0ES only if USB-C PD functionality and >5.5 V input are needed; MPF7100BVMA3ESR2 is optimized for i.MX8DXP/DX with fixed 2.7–5.5 V input. |
Compared with MPF7100BVBA3ES, MPF7100BVMA3ESR2 omits ASIL B–specific safety registers and fail-safe locking but retains identical power architecture, pinout, and I²C interface - enabling drop-in replacement in non-safety-critical designs. Against PF8100A0ES, it trades USB-C PD integration for lower cost, smaller footprint, and tighter i.MX8 optimization.

FAQ
What is the operating temperature range for MPF7100BVMA3ESR2?
MPF7100BVMA3ESR2 is rated for −40 °C to +105 °C ambient operation per AEC-Q100 Grade 2. This range supports deployment in automotive cabin and under-dash environments where thermal extremes occur, and is validated through accelerated life testing and thermal cycling per JEDEC JESD22-A104.
Does MPF7100BVMA3ESR2 support LPDDR4 memory power requirements?
Yes, MPF7100BVMA3ESR2 directly supports LPDDR4 memory with SW3 configured in VTT mode (0.4–1.8 V @ 2.5 A) and SW4 delivering VDDQ (1.1/1.35 V @ 2.5 A). Its OTP-configured sequencing ensures correct power-up order between VDD_SNVS, VDD_MAIN, and DDR rails as specified for i.MX8DXP/DX platforms.
How does the OTP memory in MPF7100BVMA3ESR2 simplify system design?
The OTP memory in MPF7100BVMA3ESR2 stores startup voltages, power-on sequencing order, soft-start timing, and safety thresholds - eliminating the need for external resistor dividers, sequencer ICs, or configuration EEPROM. This reduces BOM count, PCB area, and boot-time variability while ensuring repeatable power behavior across units.
Can MPF7100BVMA3ESR2 be used with i.MX8DX processors?
Yes, MPF7100BVMA3ESR2 is explicitly qualified for i.MX8DX and i.MX8DXP processors, as confirmed in Table 2 of the datasheet. Its regulator count, output ranges, current capabilities, and I²C interface match the power architecture requirements of both families, including support for LPDDR4 memory and dual-core operation.
What safety features are enabled in the QM-grade MPF7100BVMA3ESR2?
MPF7100BVMA3ESR2 includes thermal shutdown, overvoltage/undervoltage monitoring on all regulators, watchdog timer input (WDI), reset output (RESETBMCU), and fail-safe output (FSOB) - all functional in QM mode. However, ASIL B–specific features like ABIST on-demand, secure I²C writes, and fail-safe lock-down are disabled per device differences table.
