NXP Semiconductors MMPF0100NPZESR2

Overview

MMPF0100NPZESR2 from NXP Semiconductors is an AEC-Q100 Grade 2 automotive power management IC (PMIC) with 4–6 configurable buck converters, 6 LDOs, RTC supply, coin-cell charger, and DDR termination reference. It delivers up to 2.5 A per buck channel (SW1A/B, SW3A/B, SW2), supports i.MX 6 family processors, and operates across -40 °C to +105 °C ambient temperature in automotive infotainment systems.

For engineers reviewing the MMPF0100NPZESR2 datasheet, MMPF0100NPZESR2 pinout, MMPF0100NPZESR2 application, or MMPF0100NPZESR2 equivalent, key selection criteria include OTP-programmable startup sequencing, I²C-controlled DVS, thermal interrupt reporting (THERM110I–THERM130I), VREFDDR tracking capability, and wettable-flank QFN-56 package compatibility with automotive PCB assembly requirements.

Technical Context

The MMPF0100NPZESR2 implements a multi-rail power architecture with independent control logic for six switching regulators (SW1A/B/C, SW2, SW3A/B, SW4) and six linear regulators (VGEN1–6, VCOREDIG, VSNVS), all coordinated by an initialization state machine and programmable OTP memory. Its core control logic integrates processor interface signals (PWRON, STANDBY, RESETBMCU), event detection (INTB, SDWNB), and thermal monitoring via dedicated comparator thresholds.

It features dual clock domains (16 MHz and 32 kHz), trim-in-package references for VCORE/VCOREREF, and bias generation for DDR termination (VREFDDR) using VINREFDDR and VHALF inputs. The device supports single/dual-phase operation on SW1 and SW3 rails, DDR termination tracking mode, and boost regulation to 5.0 V via SWBST with internal current limiting.

FAQ

What is the maximum allowable input voltage for the MMPF0100NPZESR2 main supply pin (VIN)?

The absolute maximum rating for the VIN pin is 4.8 V. Operation above this voltage may cause permanent damage. The recommended operating range is 2.8 V to 4.5 V, which ensures stable regulation across automotive battery conditions including cold-crank (down to ~6 V battery) with proper upstream pre-regulation. The MMPF0100NPZESR2 includes internal overvoltage protection that disables regulators if VIN exceeds 4.8 V.

Does the MMPF0100NPZESR2 support DDR3 or DDR4 memory termination?

Yes, the MMPF0100NPZESR2 supports both DDR3 and DDR4 termination through its VREFDDR output, which provides a precision 0.6 V to 1.35 V reference with ±1.5% accuracy over temperature. The VREFDDR rail tracks VHALF (half-supply) and is internally buffered to drive DDR termination networks directly, eliminating external resistive dividers and improving signal integrity in high-speed memory interfaces.

Can the MMPF0100NPZESR2 be used without programming the OTP memory?

Yes, the MMPF0100NPZESR2 is shipped in non-programmed (NP) configuration as indicated by the "N" in the part number MMPF0100NPZESR2. In this state, it boots using default factory settings stored in ROM, enabling immediate evaluation. Full customization - including rail voltages, sequencing order, and enable timing - requires OTP programming via VDDOTP pin using NXP's official programming tools and procedures.

What thermal protection features does the MMPF0100NPZESR2 provide?

The MMPF0100NPZESR2 integrates four programmable thermal interrupt thresholds (110 °C, 120 °C, 125 °C, 130 °C) reported via dedicated bits in the INTSENSE0 register. Each threshold triggers an open-drain INTB signal to the host processor. A hardware thermal shutdown activates above 130 °C with 8 ms debounce to prevent false trips. These features are documented in Section 4.2.1 and Table 6 of the PF0100Z datasheet.

Is the MMPF0100NPZESR2 pin-compatible with the PF0100AZ variant?

No, the MMPF0100NPZESR2 (PF0100Z family) is not pin-compatible with the PF0100AZ. While both share the same 56-pin QFN package and pinout, the PF0100AZ introduces functional changes including revised OTP fuse loading logic (removal of XOR function), increased VSNVS current limit, and errata fixes (ER19/20/22). Migration requires firmware and OTP configuration updates; refer to Table 2 in the PF0100Z datasheet for full version differences.
