Product details
Overview
MC34PF3001A7EPR2 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 1.8 V/3.3 V), V33 (350 mA), and VSNVS (1.0 mA, RTC backup)-in a 48-pin QFN 7.0 mm × 7.0 mm wettable flank package. It supports industrial temperature range (−40 °C to +105 °C) and integrates coin-cell charging for always-on real-time clock operation.
For engineers reviewing the MC34PF3001A7EPR2 datasheet, MC34PF3001A7EPR2 pinout, MC34PF3001A7EPR2 application, or MC34PF3001A7EPR2 equivalent, key selection criteria include OTP-programmed startup sequence (SW1=1.4 V, SW2=3.3 V, SW3=1.35 V, VCC_SD=3.3 V/1.85 V), I²C programmability for dynamic voltage scaling, thermal and overvoltage protection, and compatibility with 2.8–4.5 V or 3.7–5.5 V input rails using optional external VPWR LDO FET.
Technical Context
The MC34PF3001A7EPR2 implements a fixed OTP-based power tree with pre-configured sequencing (SW1 SEQ=3, SW2 SEQ=3, SW3 SEQ=3, VCC_SD SEQ=3) and trimmed 16 MHz/32 kHz clocks for precise timing control during startup and regulation. Its buck regulators support PWM, PFM, and APS modes, enabling efficient operation across load ranges from light-load standby to full-core active states.
Core regulation relies on internal bandgap reference (VCOREREF), with dedicated ground references (GNDREF1, GNDREF2, GNDREF) isolating analog, digital, and switching domains. The VSNVS rail operates as either an LDO or bypass switch, configurable via coin-cell or VIN sourcing, while SD_VSEL enables runtime selection between 1.8 V and 3.3 V VCC_SD output for SD card interface compliance.

Pinout & Package
MC34PF3001A7EPR2 uses a 48-pin QFN 7.0 mm × 7.0 mm wettable flank (98ASA00933D) package with exposed thermal pad (EP). Pin functions are fixed per OTP configuration and include dedicated switch-node (SWxLX), feedback (SWxFB), input (SWxIN), and ground-reference (GNDREF1/GNDREF2/GNDREF) terminals for noise-sensitive buck regulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW1LX (pins 8,9) | Buck 1 switch node | Connects directly to SW1 inductor; requires low-inductance layout to minimize EMI and switching losses |
| SW1FB (pin 6) | SW1 output voltage feedback | High-impedance analog input; must be routed away from high-current paths and terminated near output capacitor |
| VCC_SD (pin 33) | SD card I/O regulator output | Provides 1.8 V or 3.3 V to SDIO interface; voltage set by SD_VSEL logic level at boot |
| LICELL (pin 36) | Coin-cell charge interface | Bi-directional analog terminal supporting trickle-charge and backup power path for VSNVS domain |
| INTB (pin 1) | Open-drain fault interrupt | Active-low signal asserted on overvoltage, thermal, or short-circuit events; requires external pull-up to VDDIO |
Key Features
| Feature | Design Value |
|---|---|
| OTP-configured startup sequence | Fixed timing and order (SW1→SW2→SW3→VCC_SD→VLDO4→V33) eliminates external sequencing components and reduces BOM count |
| Dual-voltage VCC_SD regulator | Hardware-selectable 1.8 V or 3.3 V output via SD_VSEL pin meets JEDEC SDIO v3.0 and eMMC 4.5 requirements |
| Integrated RTC backup with coin-cell charging | VSNVS delivers stable 3.0 V at 1.0 mA while managing Li-cell charge current and voltage limits autonomously |
| Thermal and overvoltage protection | On-die thermal shutdown (>150 °C) and VPWROV detection (>6.0 V) prevent damage during abnormal operating conditions |
| Trimmed 16 MHz oscillator | Enables precise 2.0 MHz buck switching frequency with ±3% factory-adjustable offset for EMI optimization |

FAQ
What is the default I²C address for MC34PF3001A7EPR2?
The default I²C address for MC34PF3001A7EPR2 is 0x08, as defined in its OTP configuration. This address is used for read/write access to registers controlling dynamic voltage scaling, fault masking, and operational mode selection. The address remains fixed unless modified via I²C during runtime, though factory programming ensures 0x08 is active at power-up for all A7 variants including MC34PF3001A7EPR2.
Does MC34PF3001A7EPR2 support dynamic voltage scaling (DVS) for the core rail?
Yes, MC34PF3001A7EPR2 supports dynamic voltage scaling for SW1 (core rail) with a programmable slew rate of 6.25 mV/µs, as specified in its A7 OTP configuration. This allows controlled ramping of the 1.4 V core voltage during processor frequency transitions. DVS is implemented via I²C writes to the SW1VOLT register and requires no external circuitry-enabling energy-efficient operation in i.MX 6UL-based systems running MC34PF3001A7EPR2.
How does the SD_VSEL pin affect VCC_SD output voltage in MC34PF3001A7EPR2?
In MC34PF3001A7EPR2, the SD_VSEL pin selects between two VCC_SD output ranges: logic HIGH sets 1.80–1.85 V for SDIO v3.0 compliance, while logic LOW sets 2.85–3.30 V for legacy SD card support. This selection is sampled at power-up and latched; the pin is powered by VDDIO, and defaults to HIGH if VDDIO is invalid-ensuring safe low-voltage boot. MC34PF3001A7EPR2's OTP config fixes VCC_SD_SEQ=3, making SD_VSEL critical for correct interface initialization.
What is the purpose of the LICELL pin on MC34PF3001A7EPR2?
On MC34PF3001A7EPR2, the LICELL pin provides bidirectional connection to an external coin cell (e.g., CR2032) for VSNVS domain backup. It enables autonomous trickle-charging of the cell when main power is present and seamless switchover to coin-cell power during VIN loss-maintaining RTC time and SNVS register contents. The pin includes internal current limiting and voltage regulation, and requires only a 0.1 µF bypass capacitor per datasheet guidelines for MC34PF3001A7EPR2.
Can MC34PF3001A7EPR2 operate with a 5.0 V input supply?
Yes, MC34PF3001A7EPR2 can operate with a 5.0 V input supply using the VPWR front-end LDO configuration. When VPWR is connected to 5.0 V and an external PMOS FET (e.g., FDMA908PZ) is populated, the internal LDOG driver regulates VIN to ≤4.5 V for safe buck/LDO operation. If VPWR is unused, MC34PF3001A7EPR2 must be powered via VIN with ≤4.5 V-making the VPWR path essential for 5.0 V system designs.
