Product details
Overview
MPF7100BVMA1ESR2 from NXP Semiconductors is a 7-channel automotive-grade power management IC (PMIC) designed for i.MX 8XL processors with LPDDR4 memory support. It integrates five high-efficiency buck converters (SW1–SW5), two linear regulators (LDO1/LDO2), dual RTC LDOs (VSNVS1/VSNVS2), and ASIL B–capable safety monitoring. It delivers up to 2.5 A per buck channel, supports dynamic voltage scaling, and stores startup configuration in one-time programmable (OTP) memory for reduced external component count in infotainment and telematics systems.
For engineers reviewing the MPF7100BVMA1ESR2 datasheet, MPF7100BVMA1ESR2 pinout, MPF7100BVMA1ESR2 application, or MPF7100BVMA1ESR2 equivalent, this page provides verified technical context, validated pin functions, confirmed regulator output ranges and current ratings, OTP-programmed configuration details for i.MX 8XL + LPDDR4, and real-world safety feature implementation per AEC-Q100 Grade 2 and QM functional safety classification.
Technical Context
The MPF7100BVMA1ESR2 implements a hierarchical state machine with OTP-configured power-up sequencing, self-test routines (ASIL B only), and fail-safe transitions. Its five buck regulators support multi-phase configurations - SW1/SW2 as dual-phase, SW3/SW4 as dual-phase, SW1–SW3 as triple-phase (up to 7.5 A), and SW1–SW4 as quad-phase (up to 10 A) - enabling adaptive core voltage delivery for i.MX 8XL CPU and GPU domains.
It features hardware-based safety monitoring including independent voltage fault detection (OV/UV), thermal shutdown at 150 °C, watchdog timer with configurable counter, ABIST for analog monitors, and FSOB fail-safe output. Unlike ASIL B variants, MPF7100BVMA1ESR2 is QM-rated: it omits AB_SWx_OV/UV flags, FS_CNT[3:0], OTP_FS_BYPASS, secure I2C write enable, and active safe-state assertion via FSOB.

Pinout & Package
MPF7100BVMA1ESR2 is housed in a thermally enhanced HVQFN48 package (7 mm × 7 mm × 0.85 mm body, 0.5 mm pitch, dimple wettable flanks) with exposed EPAD for improved thermal dissipation in automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW1IN–SW5IN | Buck input supply pins | Accept main VIN or locally regulated input; each must sink current during power-down to prevent overvoltage on downstream capacitors. |
| SW1LX–SW5LX | Buck switching node outputs | Connect directly to external inductors; require low-ESR ceramic output capacitors and careful layout to minimize EMI and ringing. |
| SW1FB–SW5FB | Buck feedback inputs | Resistive divider inputs for closed-loop voltage regulation; precision matching required for ≤2 % output accuracy. |
| LDO1IN/LDO2IN | LDO input supplies | Accept pre-regulated input (e.g., from buck outputs); dropout voltage determines minimum input headroom for specified load current. |
| LDO1OUT/LDO2OUT | LDO regulated outputs | Provide low-noise, low-ripple bias; optional load switch mode enables controlled power gating of peripherals. |
| VSNVS1/VSNVS2 | RTC LDO outputs | Supply always-on domains; configured via OTP to fixed voltage options - no runtime adjustment required. |
| SCL/SDA | I²C interface signals | Support standard/fast/fast-plus modes; 3.4 MHz capability allows rapid register updates during DVFS transitions. |
| PGOOD/INTB/FSOB | Open-drain status outputs | Signal power-good status, general interrupts, or fail-safe lockout; require external pull-ups to compatible logic rail (1.6–3.3 V). |
| RESETBMCU | Open-drain reset output | Asserts active-low reset to i.MX 8XL during startup failure, thermal shutdown, or critical fault - synchronized with PMIC state machine. |
| VDDIO | I/O supply voltage | Must be connected to system I/O rail (1.6–3.3 V); sets logic threshold for SCL/SDA, INTB, PGOOD, and other digital pins. |
| EPAD | Exposed thermal pad | Electrically tied to GND; requires solid thermal vias to inner ground planes for junction-to-ambient thermal resistance ≤22 °C/W (8-layer board). |
Key Features
| Feature | Design Value |
|---|---|
| OTP-configurable startup sequence | Eliminates need for external resistors, EEPROM, or FPGA-based sequencing logic - reduces BOM count and improves boot reliability. |
| Dual-phase and multi-phase buck configurations | Enables scalable current delivery: SW1/SW2 dual-phase (5 A), SW1–SW3 triple-phase (7.5 A), or SW1–SW4 quad-phase (10 A) for high-performance CPU clusters. |
| VTT termination mode on SW3 | Directly supplies DDR memory VTT rail (0.4 V to 1.8 V) with matched source/sink capability - removes need for discrete VTT regulator or resistor network. |
| Hardware watchdog with MCU interface | WDI input accepts MCU heartbeat; internal counter triggers RESETBMCU if missed - provides autonomous fail-safe recovery without software intervention. |
| Analog multiplexer (AMUX) for diagnostics | Routes internal voltage monitors (SWxVMON, LDOxVMON, die temp) to a single pin for oscilloscope or ADC sampling - simplifies system-level health monitoring. |
| ASIL B–compatible monitoring (QM variant) | Includes voltage OV/UV detection, thermal shutdown, and PGOOD supervision - meets QM requirements for non-safety-critical infotainment subsystems. |

FAQ
What is the key functional difference between MPF7100BVMA1ESR2 and MPF7100BVBA1ESR2?
The MPF7100BVMA1ESR2 is QM-rated with no ASIL B safety features enabled, while MPF7100BVBA1ESR2 is ASIL B-certified and includes ABIST, fail-safe output (FSOB) assertion, fault counters (FS_CNT), and secure I2C write protection. MPF7100BVMA1ESR2 uses the same silicon but disables safety logic via OTP configuration - making it suitable for non-safety-critical infotainment systems where certification overhead is unnecessary.
Does MPF7100BVMA1ESR2 support LPDDR4 memory power delivery out of the box?
Yes - MPF7100BVMA1ESR2 is pre-programmed with OTP configuration optimized for i.MX 8XL processors paired with LPDDR4 memory. This includes calibrated VDD_DDR_VDDQ (SW4), VTT (SW3), and VDD_1P8 (SW5) output voltages and sequencing timing, eliminating the need for field programming before integration.
What is the role of the VSELECT pin on MPF7100BVMA1ESR2?
The VSELECT pin on MPF7100BVMA1ESR2 configures LDO2 output voltage in hardware: logic low selects 1.8 V, logic high selects 3.3 V. This enables simple, resistor-free selection of common interface rails for SD card, USB PHY, or camera modules without requiring I²C writes during boot.
Can MPF7100BVMA1ESR2 operate with a 3.3 V input supply?
Yes - MPF7100BVMA1ESR2 accepts VIN from 2.7 V to 5.5 V, so a nominal 3.3 V supply is fully supported. All internal regulators (buck and LDO) are designed to function within this range, and the 3.3 V rail can directly power VDDIO and LDO2IN, simplifying system-level power architecture.
How does the AMUX pin enhance system diagnostics for MPF7100BVMA1ESR2?
The AMUX pin on MPF7100BVMA1ESR2 multiplexes internal monitor signals - including SW1–SW5 VMON, LDO1/LDO2 VMON, die temperature, and bandgap references - onto a single analog output. This allows engineers to connect one ADC channel or oscilloscope probe to validate rail stability, detect drift, or correlate thermal behavior with load transients without adding external monitoring circuitry.
