Product details
Overview
MC34PF3001A5EP from NXP Semiconductors is a fixed-configuration 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) and seven LDOs-including VCC_SD (100 mA, dual-voltage SD card support), V33 (350 mA), and VSNVS (3.0 V, 1.0 mA RTC supply)-in a 48-pin QFN 7.0 mm × 7.0 mm wettable flank package.
For engineers reviewing the MC34PF3001A5EP datasheet, MC34PF3001A5EP pinout, MC34PF3001A5EP application, or MC34PF3001A5EP equivalent, this page provides verified regulator output voltages, OTP-programmed startup sequence (SW1=1.375 V, SW2=3.15 V, SW3=1.2 V, VCC_SD=3.15 V/1.80 V), I²C address (0x08), thermal design guidance, and validated alternatives for industrial i.MX 6SL-based systems requiring stable power sequencing and coin-cell-backed RTC operation.
Technical Context
The MC34PF3001A5EP implements a fixed OTP-programmed power tree with hardwired startup timing (SEQ_CLK_SPEED = 2000 µs), dynamic voltage scaling (DVS) for SW1/SW2/SW3, and integrated 32 kHz/16 MHz clock generation-where the trimmed 16 MHz oscillator sets switching frequency (2.0 MHz default) and enables precise DVS slew rate control (12.5 mV/µs).
Its architecture integrates an optional front-end VPWR LDO using an external P-MOSFET (e.g., FDMA908PZ) for input voltages up to 5.5 V, while internal core supplies (VCOREDIG = 1.28 V in off mode, VCOREREF bandgap reference) are decoupled via dedicated pins (VCORE, VCOREDIG, VCOREREF) with strict no-load requirements.

Pinout & Package
MC34PF3001A5EP uses a 48-pin QFN 7.0 mm × 7.0 mm wettable flank package (98ASA00933D), with exposed thermal pad (EP) tied to ground plane for thermal dissipation. Pin functions follow PF3001 family specification; unused switcher pins (e.g., SW1LX, SW1IN) require specific floating/connection per datasheet Section 7.2 Note [1].
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INTB (Pin 1) | Open-drain interrupt output | Active-low fault indicator; asserts on overvoltage, thermal, or short-circuit events; requires external pull-up |
| SD_VSEL (Pin 2) | Digital input | Selects VCC_SD output range: LOW = 2.85–3.3 V, HIGH = 1.80–1.85 V; defaults HIGH if VDDIO absent |
| RESETBMCU (Pin 3) | Open-drain reset output | Deasserts 2.0 ms after final regulator enable; signals processor release from POR; not regulator-monitored |
| SW1FB (Pin 6) | Analog feedback input | Closes SW1 regulation loop; must route separately from high-current paths and terminate near output cap |
| VSNVS (Pin 34) | RTC supply output | 3.0 V always-on rail for SNVS/SRTC domain; supports coin-cell backup via LICELL pin (36) |
| LICELL (Pin 36) | Bi-directional coin-cell interface | Charges external coin cell (e.g., CR2032) when VIN present; supplies VSNVS during main power loss |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC34PF3001A6EP | OTP-configured for i.MX 6UL with LPDDR2; SW1 = 1.4 V, SW2 = 3.3 V, SW3 = 1.2 V, VCC_SD = 3.3 V/1.85 V | Targeted for i.MX 6UL-based designs; incompatible startup sequence and voltage setpoints for i.MX 6SL | Select only if migrating to i.MX 6UL SoC with identical thermal and layout constraints |
| MC33PF3001A6ES | Automotive-grade (−40 °C to 105 °C); same OTP config as A6EP but with AEC-Q100 qualification and enhanced ESD protection | Designed for automotive infotainment; higher cost and qualification overhead not justified for industrial use | Choose only for automotive deployments requiring AEC-Q100 Grade 2 compliance and extended temperature operation |

FAQ
What is the default I²C address for the MC34PF3001A5EP?
The MC34PF3001A5EP has a fixed I²C slave address of 0x08, as defined in its OTP memory. This address cannot be altered in hardware or via software and is shared across all PF3001 variants. Communication requires standard-mode (100 kHz) or fast-mode (400 kHz) I²C with open-drain SDA/SCL lines pulled up to VDDIO (1.7–3.6 V) using 4.7 kΩ resistors. The MC34PF3001A5EP does not support address selection pins or alternate addressing schemes.
How does the SD_VSEL pin configure VCC_SD output voltage on the MC34PF3001A5EP?
On the MC34PF3001A5EP, the SD_VSEL pin (Pin 2) selects VCC_SD output range: logic LOW sets 2.85–3.3 V (e.g., 3.15 V per OTP), while logic HIGH selects 1.80–1.85 V (e.g., 1.80 V). The input buffer is powered by VDDIO; if VDDIO is absent, SD_VSEL defaults HIGH, forcing 1.80 V operation. This dual-range capability enables direct interface with both legacy SD cards and UHS-I compliant peripherals without external level-shifting circuitry.
What is the startup sequence and timing for the MC34PF3001A5EP?
The MC34PF3001A5EP executes a fixed OTP-programmed startup sequence: VSNVS → SW1 → VCC_SD → VLDO4 → SW2 → SW3 → VLDO3, with SEQ_CLK_SPEED = 2000 µs. Total time from VIN > UVDET to RESETBMCU deassertion is typically 4.5 ms (min 2.5 ms, max 6.5 ms). This deterministic timing eliminates software initialization delays and ensures reliable i.MX 6SL boot under varying input conditions, critical for industrial fail-safe operation.
Can the MC34PF3001A5EP support input voltages above 4.5 V?
Yes-the MC34PF3001A5EP supports up to 5.5 V input via its optional VPWR front-end LDO, which uses an external P-MOSFET (e.g., FDMA908PZ) driven by the LDOG pin (Pin 30). When VPWR is connected to >4.5 V supply and VIN grounded, the internal error amplifier regulates VIN to ≤4.5 V. For ≤4.5 V inputs, VPWR must be grounded and VIN used directly-no external FET required. This dual-input architecture maintains regulator safety across wide industrial input ranges.
What is the role of the LICELL pin on the MC34PF3001A5EP?
The LICELL pin (Pin 36) on the MC34PF3001A5EP provides bi-directional coin-cell interfacing: it charges an external CR2032 (or similar) when main power is present and supplies VSNVS during main power loss. Internal charging circuitry limits current to safe levels, and VSNVS remains active at 3.0 V with 1.0 mA load capability. This enables >5-year RTC uptime on coin cell alone and eliminates need for discrete backup diodes or charge controllers in portable medical or industrial logging applications.
