NXP Semiconductors MMPF0200NPAEPR2

Overview

MMPF0200NPAEPR2 from NXP Semiconductors is a 12-channel configurable power management IC (PMIC) designed for i.MX 6SoloLite, i.MX 6Solo, and i.MX 6DualLite application processors. It integrates up to four buck converters (SW1A/B: 2.5 A, SW2: 1.5 A, SW3A/B: 2.5 A total), one 5.0–5.15 V / 600 mA boost regulator, six programmable LDOs (VGEN1–VGEN6), RTC supply with coin-cell charger, DDR reference (VREFDDR: 0.6–0.9 V), and I²C-controlled dynamic voltage scaling - enabling full-system power delivery in tablets, industrial control, and medical monitoring.

For engineers reviewing the MMPF0200NPAEPR2 datasheet, MMPF0200NPAEPR2 pinout, MMPF0200NPAEPR2 application, or MMPF0200NPAEPR2 equivalent, key selection criteria include OTP-configurable startup sequencing, thermal protection thresholds (110–130 °C), quiescent current as low as 4.0 μA in coin-cell mode, and support for i.MX 6 processor-specific power states including Standby, Sleep, and Off modes with programmable rail enable/disable timing.

Technical Context

The MMPF0200NPAEPR2 implements a SMARTMOS-based architecture with fully integrated power devices and minimal external components. Its three-to-four-buck topology supports flexible configuration: SW1A/B operates as dual-phase (2.5 A total) or independent outputs; SW3A/B can be single-phase (2.5 A) or split into two 1.25 A rails; SW2 delivers 1.5 A at 0.4–3.3 V. All bucks support PWM/PPM/APS modes, programmable soft-start, OCP with fault interrupt, and DVS for processor core voltage adaptation.

Control is implemented via I²C interface (SCL/SDA, 3.6 V tolerant) with OTP memory storing boot configuration, startup sequence, voltage levels, and timing. The device includes dedicated logic interfaces (PWRON, STANDBY, RESETBMCU, SDWNB, INTB), thermal monitoring (THERM110I–THERM130I interrupts), and bias/reference generation (16 MHz RC oscillator, 32 kHz clock, VCOREREF, VHALF). VSNVS provides selectable 1.0–3.0 V output from VIN or coin cell, with integrated charging circuitry.

FAQ

What is the primary application processor family supported by the MMPF0200NPAEPR2?

The MMPF0200NPAEPR2 is explicitly designed for NXP's i.MX 6 series, including i.MX 6SoloLite, i.MX 6Solo, and i.MX 6DualLite processors. Its OTP configuration, rail voltage ranges (e.g., VCOREDIG at 1.5 V, VREFDDR at 0.6–0.9 V), and I²C register map align directly with i.MX 6 boot ROM requirements and power state transitions. The MMPF0200NPAEPR2 is validated with NXP reference designs like i.MX6SX-SDB and supports full system-level power sequencing out of the box.

Does the MMPF0200NPAEPR2 include built-in DDR memory reference voltage generation?

Yes, the MMPF0200NPAEPR2 integrates a dedicated DDR voltage reference block (VREFDDR) that delivers 0.6–0.9 V at up to 10 mA with ±1% accuracy over temperature. It uses VINREFDDR as input and VHALF as half-supply bias to ensure stability. This eliminates the need for an external DDR termination IC in i.MX 6-based designs using DDR3 or LPDDR2 memory, and is a distinguishing feature versus alternatives like RT5782AZSP which lack VREFDDR.

How does the MMPF0200NPAEPR2 handle power loss and maintain RTC functionality?

The MMPF0200NPAEPR2 maintains RTC operation during main power loss via its VSNVS rail and integrated coin-cell charger. When VIN drops below UVLO, VSNVS automatically switches to LICELL input (1.8–3.3 V), delivering 1.0–3.0 V to the i.MX 6's SNVS domain. The LICELL pin supports charging of Li/MnO₂ coin cells with current limiting and end-of-charge detection - ensuring continuous RTC timekeeping and secure key storage without external circuitry.

What thermal protection features are implemented in the MMPF0200NPAEPR2?

The MMPF0200NPAEPR2 implements four programmable thermal interrupt thresholds (THERM110I to THERM130I) at 110–130 °C with 2–4 °C hysteresis, plus a hard thermal shutdown at ≥140 °C. These interrupts are reported via INTB and readable in INTSENSE0 register. The device also features debounced thermal protection (8 ms) to prevent false trips from transient spikes. This layered approach enables staged system responses - such as throttling SW1A/B before initiating full shutdown - critical for industrial and medical applications.

Is the MMPF0200NPAEPR2 pin-compatible with other PF0200 variants like MMPF0200F6AEP?

Yes, all PF0200 variants - including MMPF0200NPAEPR2, MMPF0200F6AEP, and MMPF0200F0ANES - share identical 56-pin QFN (8×8 mm) mechanical and electrical pinouts. Differences lie solely in OTP programming (NP = unprogrammed; F0/F3/F4/F6 = pre-programmed for specific i.MX 6 configurations) and qualification tier (Consumer vs. Extended Industrial temperature grade). No PCB layout changes are required when substituting between these variants.
