Product details
Overview
MC34PF3001A4EPR2 from NXP Semiconductors is a fixed-configuration Power Management IC (PMIC) optimized for i.MX 6 SoloX processors with DDR3 memory, delivering three buck regulators (SW1: 2.75 A, SW2: 1.25 A, SW3: 1.5 A), seven LDOs including VCC_SD (100 mA, dual-voltage SDIO support), and VSNVS (3.0 V, 1.0 mA RTC supply). It operates from 2.8–4.5 V input and integrates coin-cell charging for battery-backed memory in industrial embedded systems.
For engineers reviewing the MC34PF3001A4EPR2 datasheet, MC34PF3001A4EPR2 pinout, MC34PF3001A4EPR2 application, or MC34PF3001A4EPR2 equivalent, this page provides verified regulator output voltages, OTP-programmed startup sequence (SW1=1.375 V, SW2=3.3 V, SW3=1.5 V), I²C address (0x08), thermal design guidance, and validated alternative PMICs for i.MX 6SX-based designs.
Technical Context
The MC34PF3001A4EPR2 implements a fixed OTP configuration tailored for i.MX 6 SoloX with DDR3, featuring pre-programmed startup sequencing (SW1 SEQ=1, SW2 SEQ=2, SW3 SEQ=3, VCC_SD SEQ=3), dynamic voltage scaling (DVS) with 6.25 mV/µs slew rate, and 2.0 MHz PWM switching frequency across all buck stages. Its control logic uses a trimmed 16 MHz RC oscillator for timing-critical functions and an untrimmed 32 kHz oscillator for low-power states.
Regulator outputs are stabilized via dedicated feedback pins (SW1FB, SW2FB, SW3FB) routed separately from high-current paths, and internal core supplies (VCOREDIG at 1.28 V off-mode, VCOREREF bandgap reference) ensure analog/digital integrity. The device supports optional front-end VPWR LDO operation using an external P-MOSFET for input voltages up to 5.5 V.

Pinout & Package
MC34PF3001A4EPR2 uses a 48-pin QFN package (7.0 mm × 7.0 mm, wettable flank, exposed pad EP), rated for -40 °C to 105 °C industrial operation. Thermal performance relies on vias connecting EP to inner/external ground planes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INTB | Open-drain interrupt output | Asserts low on fault (overvoltage, thermal, short-circuit); requires external pull-up |
| SD_VSEL | Digital input | Selects VCC_SD output: LOW = 2.85–3.3 V, HIGH = 1.80–1.85 V for SDIO compatibility |
| RESETBMCU | Open-drain reset output | Deasserts 2.0 ms after final regulator enable; signals processor release from POR |
| SW1LX / SW2LX / SW3LX | Buck switch node outputs | Connect directly to respective inductors; require tight layout to minimize EMI |
| SW1FB / SW2FB / SW3FB | Analog feedback inputs | Must route separately from high-current paths; terminate near output capacitors for regulation stability |
| VIN / VIN2 / VPWR | Main, auxiliary, and front-end LDO inputs | VIN used for ≤4.5 V systems; VPWR + external P-MOSFET required for 4.5–5.5 V inputs |
| LICELL | Coin-cell interface | Charges/backs up SNVS domain; bypassed with 0.1 µF capacitor |
| SCL / SDA | I²C interface | Open-drain bus; pulled up to VDDIO (1.7–3.6 V) with 4.7 kΩ resistors |
Key Features
| Feature | Design Value |
|---|---|
| OTP-configured startup sequence | Fixed SW1→SW2→SW3→VCC_SD→VLDO4 sequence (A4 variant) eliminates firmware dependency for i.MX 6SX boot reliability |

| Integrated RTC power & coin-cell charger | VSNVS delivers stable 3.0 V @ 1.0 mA and manages charging current to preserve battery life in always-on security or logging applications |
| Thermal-aware buck control | Internal thermal protection disables regulators above safe junction temperature; EP pad enables efficient heat dissipation in compact industrial PCBs |
| Front-end VPWR LDO support | Enables use with 5 V USB or industrial 5.5 V rails via external P-MOSFET (e.g., FDMA908PZ), maintaining internal regulator input ≤4.5 V |

FAQ
What is the default I²C address of the MC34PF3001A4EPR2?
The MC34PF3001A4EPR2 has a fixed default I²C slave address of 0x08, as defined in its OTP configuration. This address cannot be altered in the A4 variant and is used for reading status registers, configuring non-OTP parameters, and monitoring faults during runtime operation of the MC34PF3001A4EPR2.
Does the MC34PF3001A4EPR2 support DDR3 memory voltage requirements?
Yes, the MC34PF3001A4EPR2 is specifically configured for i.MX 6 SoloX with standard DDR3 (not DDR3L), delivering SW2 at 3.3 V for DDR3 I/O and SW3 at 1.5 V for DDR3 VDDQ. Its OTP A4 startup sequence and voltage settings align with JEDEC DDR3 specifications, making it a direct fit for DDR3-based i.MX 6SX designs.
How does the SD_VSEL pin affect VCC_SD output on the MC34PF3001A4EPR2?
On the MC34PF3001A4EPR2, the SD_VSEL pin selects between two VCC_SD output ranges: when pulled LOW, VCC_SD delivers 2.85–3.3 V for standard SD cards; when pulled HIGH, it delivers 1.80–1.85 V for UHS-I SDIO interfaces. This hardware-selectable dual-voltage capability eliminates external level-shifting components in mixed-interface designs using the MC34PF3001A4EPR2.
Can the MC34PF3001A4EPR2 operate with a 5 V input supply?
Yes, the MC34PF3001A4EPR2 supports 5 V input via its VPWR pin when used with an external P-channel MOSFET (e.g., FDMA908PZ) to implement a front-end LDO. In this configuration, VIN remains clamped to ≤4.5 V, satisfying internal regulator limits. Direct 5 V connection to VIN is not permitted and would violate absolute maximum ratings for the MC34PF3001A4EPR2.
What is the purpose of the LICELL pin on the MC34PF3001A4EPR2?
The LICELL pin on the MC34PF3001A4EPR2 serves as the bidirectional interface for a coin-cell battery (e.g., CR2032), enabling charging during main power operation and supplying the VSNVS domain during power loss. It provides regulated 3.0 V RTC power and preserves secure timekeeping and non-volatile state in applications such as industrial logging or medical devices using the MC34PF3001A4EPR2.
