Product details
Overview
MPF7100BVBA1ES from NXP Semiconductors is a 7-channel automotive-grade PMIC designed specifically for i.MX 8XL processors with LPDDR4 memory support. It integrates five high-efficiency buck converters (SW1–SW5), two linear regulators (LDO1/LDO2), and dual RTC LDOs (VSNVS1/VSNVS2), delivering up to 2.5 A per buck channel and supporting ASIL B functional safety. It powers core processor domains, DDR memory, and peripherals in infotainment and telematics systems.
For engineers reviewing the MPF7100BVBA1ES datasheet, MPF7100BVBA1ES pinout, MPF7100BVBA1ES application, or MPF7100BVBA1ES equivalent, this device requires attention to its OTP-programmed startup configuration for i.MX 8XL + LPDDR4, its 48-pin HVQFN48 package thermal constraints, its 3.4 MHz I²C interface for dynamic voltage scaling, and its fail-safe state machine transitions under fault conditions.
Technical Context
The MPF7100BVBA1ES implements a deterministic state machine with ASIL B–compliant self-test routines, including ABIST, CRC-verified mirror register loading, and thermal/fault monitoring that triggers FSOB assertion or hard reset. Its regulator control supports dynamic voltage scaling on SW1–SW4, VTT termination on SW3, and configurable multi-phase operation (dual/triple/quad phase) across buck channels.
It features hardware-managed power sequencing via one-time programmable (OTP) memory, eliminating external resistors for voltage setpoints and startup order. The 3.4 MHz I²C interface enables real-time reconfiguration of output voltages, soft-start timing, and protection thresholds after boot - critical for adaptive power states in automotive multimedia SoCs.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| SCL/SDA | I²C interface signals | 3.4 MHz capable; require pull-up to VDDIO (1.6–3.3 V); support register read/write, OTP programming, and real-time tuning |
| FSOB | Fail-safe output pin | Open-drain active-low output asserting during critical faults (thermal shutdown, register corruption, watchdog timeout) - connects to MCU safety controller |
| RESETBMCU | MCU reset output | Open-drain reset signal released only after successful power-up sequence and self-test completion - ensures deterministic SoC boot |
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 |
|---|---|---|---|
| MPF7100BVBA2ES | OTP-configured for i.MX 8XL + DDR3L memory (not LPDDR4); identical ASIL B safety features and pinout | Targets legacy DDR3L-based i.MX 8XL designs; incompatible with LPDDR4 VDDQ/VTT voltage profiles and timing | Select only if DDR3L memory is used; verify VDDQ = 1.35 V and VTT = 0.675 V compliance in design |
| MPF7100BVBA3ES | OTP-configured for i.MX 8DXP/DX processors with LPDDR4; same HVQFN48 package and ASIL B certification | Designed for i.MX 8DX family - different core voltage requirements (e.g., VDD_CORE = 0.8–1.1 V vs. i.MX 8XL's 0.7–1.0 V) and DDR PHY interface | Not interchangeable with MPF7100BVBA1ES; requires full SoC-specific OTP validation and power tree review |
Compared with MPF7100BVBA1ES, MPF7100BVBA2ES supports DDR3L memory systems but lacks LPDDR4-optimized VDDQ/VTT settings, while MPF7100BVBA3ES targets i.MX 8DXP/DX SoCs with distinct core voltage ranges - neither offers drop-in compatibility for i.MX 8XL + LPDDR4 without OTP and schematic revision.

FAQ
What is the primary target processor for MPF7100BVBA1ES?
The MPF7100BVBA1ES is specifically OTP-programmed for the i.MX 8XL processor with LPDDR4 memory interface. Its voltage rails - including VDD_MAIN (1.0 V), VDD_DDR_VDDQ (1.1 V/1.35 V), and VTT (0.4–1.8 V) - match i.MX 8XL's core, DDR, and termination requirements. Using it with other i.MX 8 variants (e.g., i.MX 8DX or i.MX 8QM) requires verification of OTP configuration and rail compatibility, as MPF7100BVBA1ES is not a generic drop-in replacement.
Does MPF7100BVBA1ES support dynamic voltage scaling (DVS)?
Yes, MPF7100BVBA1ES supports DVS on buck regulators SW1 through SW4 via its 3.4 MHz I²C interface. Each buck channel can be reconfigured in real time with 6.25 mV resolution across its full range (0.4 V–1.8 V), enabling adaptive core voltage scaling during i.MX 8XL performance state transitions. SW5 does not support DVS but provides fixed or OTP-programmed output for auxiliary rails.
How does the ASIL B safety functionality manifest in MPF7100BVBA1ES?
MPF7100BVBA1ES implements ASIL B compliance through ABIST (analog built-in self-test), CRC-verified OTP/mirror register loading, independent voltage/thermal monitoring with programmable fault thresholds, and a dedicated fail-safe output (FSOB) that asserts low during critical failures. Its state machine enforces safe transitions - such as locking into fail-safe state upon three consecutive self-test failures - ensuring predictable behavior under fault conditions required for automotive safety goals.
What is the role of the VSELECT pin on MPF7100BVBA1ES?
The VSELECT pin (Pin 48) configures the output voltage of LDO2 on MPF7100BVBA1ES. When pulled high or low, it selects between two factory-programmed LDO2 output levels (e.g., 1.8 V or 3.3 V), providing hardware-selectable flexibility for different peripheral I/O voltage requirements without I²C intervention. This pin must be terminated to a valid logic level (GND or VDDIO) during operation; floating is not permitted.
Can MPF7100BVBA1ES be used in non-automotive applications?
Yes, MPF7100BVBA1ES is qualified for AEC-Q100 Grade 2 (−40 °C to +105 °C), making it suitable for demanding industrial environments. Its ASIL B safety features, robust thermal management (150 °C max junction), and OTP-configured reliability also benefit high-end consumer and medical edge devices. However, its OTP content is fixed for i.MX 8XL + LPDDR4 - non-automotive users must validate whether this configuration meets their specific SoC and memory interface requirements.
