NXP Semiconductors MC32PF3001A2EP

Overview

MC32PF3001A2EP from NXP Semiconductors is a pre-programmed Power Management IC (PMIC) optimized for i.MX 7 processors with LPDDR3 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 enables full power sequencing for multimedia application processors in resource-constrained embedded systems.

For engineers reviewing the MC32PF3001A2EP datasheet, MC32PF3001A2EP pinout, MC32PF3001A2EP application, or MC32PF3001A2EP equivalent, this page delivers verified regulator output voltages, OTP-configured startup sequence (SW1=1.10 V, SW2=1.8 V, SW3=1.2 V), I²C programmability, dynamic voltage scaling support, and thermal-safe operation across –40 °C to +85 °C industrial temperature range.

Technical Context

The MC32PF3001A2EP implements fixed OTP-based power sequencing (SW1_SEQ=1, SW2_SEQ=2, SW3_SEQ=5) with 2.0 MHz PWM switching frequency across all three buck regulators and supports dynamic voltage scaling via I²C-controlled DACs. Its internal 16 MHz trimmed oscillator governs regulator timing and switching, while a dedicated 32 kHz clock manages low-power states and reset timing.

It integrates an always-on VSNVS rail (3.0 V, 1.0 mA) with coin-cell charging capability, a VPWR front-end LDO interface for >4.5 V inputs using external P-MOSFET, and logic-level control signals (PWRON, RESETBMCU, INTB, SD_VSEL) for direct coupling to i.MX 7 SoCs-enabling deterministic boot, fault reporting, and SD card voltage selection without host software intervention.

FAQ

What is the default I²C address for MC32PF3001A2EP?

The default I²C address for MC32PF3001A2EP is 0x08, as specified in Table 4 of the PF3001 datasheet Rev. 5.1. This address is factory-trimmed and cannot be altered. All register reads and writes-including voltage configuration, fault status polling, and DVS control-must target 0x08 unless modified via OTP programming during manufacturing. The MC32PF3001A2EP uses open-drain SDA/SCL with 4.7 kΩ pull-ups to VDDIO.

How does MC32PF3001A2EP support i.MX 7 with LPDDR3 memory?

MC32PF3001A2EP supports i.MX 7 with LPDDR3 through its A2 OTP configuration: SW1 delivers 1.10 V @ 2.75 A for the ARM Cortex-A7 core, SW2 supplies 1.8 V @ 1.25 A for SOC logic and LPDDR3 I/O, and SW3 provides 1.2 V @ 1.5 A for LPDDR3 termination and auxiliary domains. Its fixed startup sequence (SW1→SW2→V33→VLDO4→SW3) matches i.MX 7 LPDDR3 power-up timing requirements without host intervention.

Can MC32PF3001A2EP operate with a 5.0 V input supply?

Yes, MC32PF3001A2EP can operate with a 5.0 V input supply by enabling the optional front-end VPWR LDO: connect VPWR to 5.0 V, populate an external P-MOSFET (e.g., FDMA908PZ), and tie LDOG to its gate. This regulates VIN to ≤4.5 V, protecting internal regulators. If using ≤4.5 V input, leave VPWR grounded and route supply directly to VIN-no external FET required. Both configurations are supported per datasheet Section 8.3.5.

What is the purpose of the SD_VSEL pin on MC32PF3001A2EP?

The SD_VSEL pin on MC32PF3001A2EP selects the output voltage range of the VCC_SD LDO: logic high (SD_VSEL=1) sets 1.80–1.85 V for SDIO/eMMC interfaces, while logic low (SD_VSEL=0) sets 2.85–3.30 V for legacy SD card compatibility. This hardware-selectable feature eliminates need for external level shifters or dual-LDO designs, allowing one MC32PF3001A2EP variant to serve multiple storage interface standards.

Does MC32PF3001A2EP include thermal protection?

Yes, MC32PF3001A2EP includes thermal protection: it asserts the INTB pin low when die temperature exceeds the thermal shutdown threshold, and disables all regulators except VSNVS to prevent damage. The thermal fault is latched and requires I²C register write to clear. Thermal monitoring is continuous and independent of operating mode. This behavior is confirmed in Section 8.3.2 and Table 148 of the PF3001 datasheet Rev. 5.1.
