Product details
Overview
MC34PF3001A7EP from NXP Semiconductors is a fixed-configuration Power Management IC (PMIC) optimized for i.MX 6UL processors with DDR3L memory, delivering three buck regulators (SW1: 2.75 A, SW2: 1.25 A, SW3: 1.5 A) and seven LDOs-including VCC_SD (100 mA, dual-voltage SD card support), V33 (350 mA), and VSNVS (1.0 mA RTC supply)-in a 48-pin QFN 7.0 mm × 7.0 mm wettable flank package rated for -40 °C to 105 °C industrial operation.
For engineers reviewing the MC34PF3001A7EP datasheet, MC34PF3001A7EP pinout, MC34PF3001A7EP application, or MC34PF3001A7EP equivalent, this page provides verified regulator output voltages (e.g., SW1 = 1.4 V, SW2 = 3.3 V, SW3 = 1.35 V per OTP A7 configuration), I²C programmability, dynamic voltage scaling, coin-cell backup capability, and thermal/overvoltage protection details essential for i.MX 6UL-based embedded system power design.
Technical Context
The MC34PF3001A7EP implements a fixed OTP startup sequence (SW1_SEQ=3, SW2_SEQ=3, SW3_SEQ=3, VCC_SD_SEQ=3) with 2.0 MHz switching frequency across all buck regulators, using a trimmed 16 MHz RC oscillator for timing-critical functions including DVS ramp rate (6.25 mV/μs) and startup sequencing controlled by a 32 kHz derived clock.
Its power architecture integrates an optional front-end VPWR LDO (enabled via external P-MOSFET) for input voltages up to 5.5 V, while internal core supplies VCOREDIG (1.28 V in off mode) and VCOREREF (bandgap reference) are decoupled per spec; fault detection includes VPWROV interrupt (INTSTAT3 bit 2) and open-drain INTB assertion on unmasked faults.

| MC33PF3001A7ES | Same OTP A7 configuration and pinout; automotive-grade (-40 °C to 105 °C) with AEC-Q100 qualification | Targeted for automotive infotainment and ADAS systems requiring automotive qualification | Select MC33PF3001A7ES only if AEC-Q100 compliance is mandatory; otherwise MC34PF3001A7EP is optimal for industrial use. |
| PF0100A100EP | Legacy NXP PMIC for i.MX 6SoloX; lacks VCC_SD dual-voltage support and coin-cell charging; 40-pin QFN | Suitable for simpler i.MX 6SX designs without SD card or RTC backup requirements | Choose PF0100A100EP only for cost-sensitive, non-RTC, non-SD applications; MC34PF3001A7EP offers superior integration and flexibility. |
Compared with MC33PF3001A7ES, MC34PF3001A7EP omits AEC-Q100 testing but retains identical electrical performance and OTP configuration-making it ideal for industrial deployments where automotive qualification adds unnecessary cost. Versus PF0100A100EP, MC34PF3001A7EP adds critical SDIO voltage flexibility and battery-backed RTC, enabling next-generation edge device functionality.

FAQ
What is the default I²C address for the MC34PF3001A7EP?
The MC34PF3001A7EP uses a fixed default I²C address of 0x08, which is factory-programmed in OTP and cannot be altered. This address allows immediate communication upon power-up without requiring address configuration, simplifying system initialization in i.MX 6UL-based designs where multiple PMICs are not deployed on the same bus.
Does the MC34PF3001A7EP support dynamic voltage scaling (DVS) for the core rail?
Yes, the MC34PF3001A7EP supports dynamic voltage scaling for SW1 (core rail) with a programmable slew rate of 6.25 mV/μs per OTP configuration A7. This enables controlled voltage transitions during processor frequency changes, reducing transient current spikes and improving power efficiency in variable-workload industrial applications.
How does the MC34PF3001A7EP handle power loss to maintain RTC time?
The MC34PF3001A7EP maintains RTC time during main power loss using its VSNVS regulator and integrated coin-cell charger. When VIN drops below UVDET, the IC automatically switches VSNVS supply from VIN to the external coin cell connected to LICELL, delivering 3.0 V at 1.0 mA while simultaneously trickle-charging the cell when main power is restored.
Can the MC34PF3001A7EP operate with a 5.0 V input supply?
Yes, the MC34PF3001A7EP supports 5.0 V input via the VPWR pin when used with an external P-channel MOSFET (e.g., FDMA908PZ) and associated resistive divider. This activates the front-end LDO, regulating VIN to ≤4.5 V for internal regulator safety-enabling compatibility with standard 5 V industrial power rails without derating.
What is the purpose of the SD_VSEL pin on the MC34PF3001A7EP?
The SD_VSEL pin on the MC34PF3001A7EP selects the output voltage range of the VCC_SD regulator: logic high sets 1.80–1.85 V for UHS-I SD cards, while logic low sets 2.85–3.30 V for legacy SDIO peripherals. This eliminates external voltage translators and ensures compliance with both SD card standards in a single hardware design.
