Product details
Overview
MC34PF3001A5EPR2 from NXP Semiconductors is a pre-programmed Power Management IC (PMIC) optimized for i.MX 6 SoloLite processors with LPDDR2 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 1.8 V/3.15 V output), and RTC backup with coin cell charging - used in industrial embedded systems requiring tightly sequenced multi-rail power.
For engineers reviewing the MC34PF3001A5EPR2 datasheet, MC34PF3001A5EPR2 pinout, MC34PF3001A5EPR2 application, or MC34PF3001A5EPR2 equivalent, this page provides verified regulator voltage ranges, OTP-configured startup sequence (SW1_SEQ=1, SW2_SEQ=2, VCC_SD_SEQ=2), I²C address (0x08), thermal management guidance, and validated alternatives for i.MX 6SL-based designs.
Technical Context
The MC34PF3001A5EPR2 implements fixed OTP-based power sequencing tailored for i.MX 6 SoloLite with LPDDR2: SW1 powers the ARM core at 1.375 V (SEQ=1), SW2 supplies I/O at 3.15 V (SEQ=2), and VCC_SD delivers SD card interface voltage (1.80 V or 3.15 V depending on SD_VSEL state). Startup timing is governed by a trimmed 32 kHz clock with SEQ_CLK_SPEED = 2000 µs.
All three buck regulators support dynamic voltage scaling (DVS) with programmable slew rate (12.5 mV/µs), operate in PWM/APS/PFM modes, and share a 2.0 MHz switching frequency derived from the trimmed 16 MHz RC oscillator. The VSNVS rail provides 3.0 V @ 1.0 mA for SNVS/SRTC circuitry and supports coin cell backup via LICELL pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.8–4.5 V (VIN) or 3.7–5.5 V (VPWR with external PMOS); determines front-end LDO usage and system supply compatibility |
| SW1 Output | 1.375 V @ 2.75 A (OTP-configured for i.MX 6SL core); fixed startup voltage, programmable via I²C during operation |
| VCC_SD Output | 1.80 V or 3.15 V @ 100 mA (selected by SD_VSEL logic level); supports high-speed SD card interface voltage requirements |
| I²C Address | 0x08 (default OTP address); enables communication for runtime DVS, fault monitoring, and register configuration |
| Startup Sequence | SW1→SW2→VCC_SD→VLDO4→VLDO3 (SEQ values 1→2→2→3→2); ensures safe power-up order for i.MX 6SL + LPDDR2 memory subsystem |
| Thermal Package | 48-pin QFN 7.0 mm × 7.0 mm WF-type (wettable flank); EP pad tied to ground plane for enhanced thermal dissipation in industrial ambient (−40 °C to 105 °C) |
| RTC Supply | VSNVS = 3.0 V @ 1.0 mA with integrated coin cell charger; maintains secure non-volatile storage and real-time clock during main power loss |
Pinout & Package
MC34PF3001A5EPR2 uses a 48-pin QFN 7.0 mm × 7.0 mm package with wettable flank (98ASA00933D), featuring an exposed thermal pad (EP) connected to GND for efficient heat transfer in industrial applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW1IN / SW1LX / SW1FB | Buck regulator 1 power path | SW1IN accepts input (bypassed with 4.7 µF + 0.1 µF), SW1LX connects to inductor switch node, SW1FB provides feedback for closed-loop regulation of 1.375 V core rail |
| SD_VSEL | Digital input control | Selects VCC_SD output: logic low → 3.15 V, logic high → 1.80 V; critical for SDIO interface compliance with different memory cards |
| INTB | Open-drain interrupt output | Active-low signal asserted on fault (overvoltage, thermal, short-circuit); requires external pull-up to VDDIO (1.7–3.6 V) |
| RESETBMCU | Open-drain reset output | Deasserted 2.0 ms after final regulator enable; synchronizes i.MX 6SL exit from POR, not monitored per-rail |
| LICELL | Bi-directional coin cell interface | Charges external coin cell when VIN is present; supplies VSNVS during main power loss; bypassed with 0.1 µF capacitor |
| PWRON | Level-sensitive enable input | High-level signal initiates startup if VIN > UVDET (typically 2.5 V); defines turn-on event boundary for sequencing |
| SCL / SDA | I²C interface pins | Standard open-drain bus (pull-up to VDDIO); supports runtime reconfiguration of DVS, fault masks, and regulator enable/disable |
| EP (exposed pad) | Thermal & ground reference | Must be soldered to inner/external GND planes via multiple vias; primary thermal path for 2.75 A SW1 and total 7.5 A regulator load |
Key Features
| Feature | Design Value |
|---|---|
| OTP-configured power tree | Fixed startup sequence and voltages for i.MX 6SL + LPDDR2 (A5 variant), eliminating external configuration EEPROM and reducing BOM count |
| Dual-range VCC_SD LDO | Hardware-selectable 1.80 V or 3.15 V output via SD_VSEL pin - meets JEDEC SDIO voltage specs for both UHS-I and legacy cards |
| Integrated RTC power with charging | VSNVS rail delivers stable 3.0 V @ 1.0 mA and charges external coin cell through LICELL pin, enabling secure timekeeping during brownouts |
| Front-end VPWR LDO option | Supports up to 5.5 V input using external PMOS (e.g., FDMA908PZ); internal LDOG gate driver and VPWROV overvoltage detection protect system integrity |
| Trimmed 16 MHz oscillator | Provides stable 2.0 MHz buck switching frequency; factory-trimmable ±3% for EMI optimization without external crystal |
| Multi-mode buck regulation | Configurable PWM/APS/PFM operation per regulator - APS enables light-load efficiency (PFM-like) while maintaining PWM responsiveness under transient loads |

FAQ
What is the default I²C address for MC34PF3001A5EPR2?
The MC34PF3001A5EPR2 uses a fixed default I²C address of 0x08, programmed into OTP memory during manufacturing. This address cannot be changed in the field and is used for all runtime register access, including DVS control, fault status reads, and enable/disable commands. The address is shared across all PF3001 variants unless modified via custom programming - which is not supported for standard orderables like MC34PF3001A5EPR2.
How does the SD_VSEL pin affect VCC_SD output voltage on MC34PF3001A5EPR2?
On MC34PF3001A5EPR2, the SD_VSEL pin selects between two factory-programmed VCC_SD output voltages: logic low (≤0.8 V) sets 3.15 V for standard SDIO operation, while logic high (≥1.7 V) selects 1.80 V for UHS-I mode compatibility. The selection occurs at power-up and remains fixed until reset; the pin is buffered by VDDIO, so VCC_SD defaults to 1.80 V if VDDIO is absent during startup.
What is the startup sequence order for MC34PF3001A5EPR2?
The MC34PF3001A5EPR2 executes a fixed OTP-defined startup sequence: SW1 (core, SEQ=1) → SW2 (I/O, SEQ=2) → VCC_SD (SEQ=2) → VLDO4 (SEQ=3) → VLDO3 (SEQ=2). Timing is controlled by a trimmed 32 kHz clock with SEQ_CLK_SPEED = 2000 µs, resulting in ~4.5 ms delay between first and last enabled rail. RESETBMCU deasserts 2.0 ms after VLDO3 enable, signaling full power readiness to the i.MX 6SL processor.
Can MC34PF3001A5EPR2 support input voltages above 4.5 V?
Yes - MC34PF3001A5EPR2 supports up to 5.5 V input via the VPWR pin when used with an external P-MOSFET (e.g., FDMA908PZ) and LDOG gate driver. In this configuration, the internal front-end LDO regulates VIN to ≤4.5 V for downstream regulators. If input is ≤4.5 V, VPWR must be grounded and VIN used directly. Overvoltage protection (VPWROV threshold ≈6.0 V) triggers INTB assertion and sets INTSTAT3 bit 2.
What thermal design considerations apply to MC34PF3001A5EPR2?
MC34PF3001A5EPR2 requires direct thermal connection of its exposed pad (EP) to internal and external GND planes using ≥6 thermal vias (0.3 mm diameter) to maintain junction temperature within −40 °C to 105 °C ambient. Total power dissipation exceeds 2.5 W under full 2.75 A SW1 + 1.25 A SW2 + 1.5 A SW3 load; recommended copper area is ≥250 mm² per layer. No DC loading is permitted on VCORE, VCOREDIG, or VCOREREF pins.
