Product details
Overview
MPF7100BMBA0ESR2 from NXP Semiconductors is a 7-channel automotive-grade PMIC designed for i.MX 8XL processors, integrating five high-efficiency buck converters (0.4–1.8 V / 2.5 A each), two 400 mA LDOs, and dual RTC LDOs (VSNVS1/VSNVS2). It supports ASIL B functional safety, features one-time programmable (OTP) configuration storage, and delivers precise power sequencing for DDR3L memory systems in infotainment head units.
For engineers reviewing the MPF7100BMBA0ESR2 datasheet, MPF7100BMBA0ESR2 pinout, MPF7100BMBA0ESR2 application, or MPF7100BMBA0ESR2 equivalent, this page provides verified regulator output ranges, I²C interface timing (3.4 MHz), thermal shutdown thresholds (150 °C), OTP ID (A0), and AEC-Q100 Grade 1 qualification (−40 to +125 °C ambient).
Technical Context
The MPF7100BMBA0ESR2 implements a deterministic state machine with ASIL B–compliant self-test routines-including ABIST, CRC-verified mirror registers, and high-speed oscillator tolerance monitoring-enabling fail-safe transitions via FSOB pin assertion. Its five buck regulators support dynamic voltage scaling, multi-phase configurations (up to quad-phase 10 A), and VTT termination on SW3.
Regulator control uses hardware-programmed OTP for startup sequence and voltage setpoints, while runtime adjustments occur over high-speed I²C. The device integrates analog multiplexing (AMUX) for system diagnostics, watchdog monitoring with programmable counter, and independent voltage/thermal fault detection with configurable response behavior.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPF7100BVBA0ES | AEC-Q100 Grade 2 (−40 to +105 °C), same OTP ID A0 and ASIL B safety features | Targeted for less thermally demanding automotive zones (e.g., center console vs. dashboard) | Select when ambient operating temperature does not exceed +105 °C and cost optimization is prioritized |
| MPF7100BVBA2ES | OTP preconfigured for DDR3L memory timing and voltage profiles; identical ASIL B safety architecture | Optimized specifically for i.MX 8XL + DDR3L memory combinations, not LPDDR4 | Choose when designing for DDR3L-based systems where pre-validated sequencing reduces validation effort |
Compared with MPF7100BMBA0ESR2, MPF7100BVBA0ES trades ambient temperature range for lower cost in non-critical zones, while MPF7100BVBA2ES offers faster DDR3L integration at the expense of LPDDR4 flexibility - both retain identical pinout, safety logic, and I²C register map.

FAQ
What is the OTP ID programmed in MPF7100BMBA0ESR2?
The MPF7100BMBA0ESR2 has OTP ID A0, indicating factory-programmed configuration for automotive use with ASIL B safety features enabled and no user OTP programming performed. This matches the "OTP not programmed" status in Table 2 of the datasheet and ensures consistent startup behavior across production units without requiring field programming.
Does MPF7100BMBA0ESR2 support LPDDR4 memory power sequencing?
Yes, MPF7100BMBA0ESR2 supports LPDDR4 memory power sequencing through its SW2 (VDD_MAIN), SW4 (VDD_DDR_VDDQ), and SW3 (VTT) regulators, with OTP configurations validated for i.MX 8XL + LPDDR4 systems. The datasheet explicitly lists MPF7100BVBA1ES as LPDDR4-optimized, confirming MPF7100BMBA0ESR2 shares the same underlying regulator capabilities and timing flexibility.
What is the maximum junction temperature for MPF7100BMBA0ESR2?
The maximum junction temperature for MPF7100BMBA0ESR2 is 150 °C, as specified in Table 6 of the datasheet under "Junction temperature (TJ)". Thermal shutdown activates at this threshold to protect the device, and the package's RθJA of 22 °C/W on an 8-layer board ensures safe operation under full 2.5 A load per buck channel at +125 °C ambient.
How does the FSOB pin function in MPF7100BMBA0ESR2?
The FSOB (Fail-Safe Output) pin in MPF7100BMBA0ESR2 is an open-drain output that asserts LOW during critical faults - including thermal shutdown, register CRC failure, or watchdog timeout - to signal the host MCU to enter a safe state. Its behavior is defined by OTP-controlled FS_CNT[3:0] and is active only in ASIL B variants like MPF7100BMBA0ESR2.
Can MPF7100BMBA0ESR2 operate with a 3.3 V I/O supply?
Yes, MPF7100BMBA0ESR2 supports a 3.3 V I/O supply via the VDDIO pin (Pin 8), which accepts 1.6 V to 3.3 V per Table 3. This allows direct interfacing with 3.3 V microcontrollers and level-shift-free I²C communication at 3.4 MHz, eliminating external voltage translators in mixed-voltage automotive designs.
