Product details
Overview
MPF7100BVBA2ES from NXP Semiconductors is a 7-channel automotive-grade PMIC designed specifically for i.MX 8XL processors with DDR3L memory support. It integrates five high-efficiency buck converters (SW1–SW5), two linear regulators (LDO1/LDO2), and two RTC LDOs (VSNVS1/VSNVS2), all configurable via 3.4 MHz I²C. Its OTP-programmed startup sequence powers processor cores, DDR3L memory, and peripherals while meeting ASIL B functional safety requirements.
For engineers reviewing the MPF7100BVBA2ES datasheet, MPF7100BVBA2ES pinout, MPF7100BVBA2ES application, or MPF7100BVBA2ES equivalent, this device delivers deterministic power sequencing, real-time voltage monitoring, thermal protection, and fail-safe state transitions critical for automotive infotainment and telematics systems requiring AEC-Q100 Grade 2 operation (−40 °C to +105 °C).
Technical Context
The MPF7100BVBA2ES implements a safety-critical state machine with ASIL B compliance, including ABIST, CRC-protected register loading, programmable fault counters, and fail-safe output (FSOB) assertion on critical failures. Its architecture supports dynamic voltage scaling across SW1–SW4, VTT termination on SW3, and triple/quad-phase configurations up to 7.5 A or 10 A total current.
Regulator control is managed through OTP-configured boot settings and runtime I²C reconfiguration. The device features dual 1.6 V core supplies (V1P5A/V1P5D), analog/digital ground separation, and an integrated 20 MHz clock generator with 100 kHz derivative for timing-critical subsystems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPF7100BVBA1ES | OTP preconfigured for LPDDR4 memory (not DDR3L); identical ASIL B safety features and pinout | Targeted at i.MX 8XL systems with LPDDR4; incompatible with DDR3L VDDQ/VTT timing and voltage profiles | Select MPF7100BVBA1ES only when LPDDR4 memory is used; MPF7100BVBA2ES is mandatory for DDR3L compatibility |
| MPF7100BVBA3ES | OTP preconfigured for i.MX 8DXP/DX processors; same ASIL B qualification and HVQFN48 package | Designed for i.MX 8DX-series SoCs with different core voltage requirements and DDR topology; not validated for i.MX 8XL DDR3L use | Use MPF7100BVBA3ES only with i.MX 8DXP/DX platforms; MPF7100BVBA2ES ensures correct sequencing and regulation for i.MX 8XL + DDR3L |

FAQ
What is the primary target processor for MPF7100BVBA2ES?
MPF7100BVBA2ES is specifically designed for the i.MX 8XL application processor with DDR3L memory interface. Its OTP configuration defines voltage levels, sequencing order, and timing parameters optimized for this SoC's power architecture - including dedicated VTT termination and DDR3L-compatible VDDQ ramp rates. Using MPF7100BVBA2ES with other i.MX variants requires validation of OTP settings and regulator mapping.
Does MPF7100BVBA2ES support dynamic voltage scaling (DVS)?
Yes, MPF7100BVBA2ES supports DVS on buck regulators SW1–SW4 via I²C commands, allowing real-time adjustment of output voltages in 6.25 mV steps. This enables adaptive power management for i.MX 8XL CPU and GPU performance states. SW5 does not support DVS but offers wide-range static configuration (1.0 V–4.1 V) for auxiliary rails.
How does MPF7100BVBA2ES meet ASIL B functional safety requirements?
MPF7100BVBA2ES meets ASIL B through integrated ABIST, CRC-verified OTP/register loading, independent voltage/thermal monitors, fail-safe output (FSOB), and a deterministic state machine with lock-down capability on critical faults. These features are enabled by default in ASIL B-grade OTP images like MPF7100BVBA2ES and verified per ISO 26262 Part 5.
What is the role of the VSELECT pin on MPF7100BVBA2ES?
The VSELECT pin on MPF7100BVBA2ES configures LDO2 output voltage in hardware: logic low selects 1.8 V, logic high selects 3.3 V. This allows board-level selection without I²C interaction, supporting fixed-peripheral biasing (e.g., SD card interface at 3.3 V or sensor interface at 1.8 V) while maintaining ASIL B-compliant startup integrity.
Can MPF7100BVBA2ES be used with LPDDR4 memory instead of DDR3L?
No - MPF7100BVBA2ES is OTP-programmed for DDR3L-specific voltage sets (e.g., VDDQ = 1.35 V, VTT = 0.675 V) and timing. For LPDDR4, NXP specifies MPF7100BVBA1ES, which uses different VDDQ (1.1 V), VTT (0.55 V), and sequencing delays. Substituting MPF7100BVBA2ES risks memory initialization failure or data corruption due to mismatched regulation and timing.
