Product details
Overview
MC33PF3001A7ESR2 from NXP Semiconductors is a fixed-configuration power management IC (PMIC) designed specifically 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 VSNVS (3.0 V, 1.0 mA) and battery-backed coin cell charging-within a 48-pin QFN 7.0 mm × 7.0 mm wettable flank package. It supports automotive-grade operation from −40 °C to +105 °C.
For engineers reviewing the MC33PF3001A7ESR2 datasheet, MC33PF3001A7ESR2 pinout, MC33PF3001A7ESR2 application, or MC33PF3001A7ESR2 equivalent, this page provides verified regulator output ranges (e.g., SW1: 0.7–1.425 V, SW2: 1.5–1.85 V or 2.5–3.3 V), I²C programmability, OTP-configured startup sequencing, dynamic voltage scaling, and validated thermal design guidance for i.MX-based automotive infotainment and telematics systems.
Technical Context
The MC33PF3001A7ESR2 implements a fixed OTP-programmed power tree optimized for i.MX 6UL with DDR3L: SW1 supplies core voltage (1.4 V default), SW2 powers I/O domains (3.3 V default), and SW3 delivers memory interface rails (1.35 V default), all operating at 2.0 MHz switching frequency. Startup sequencing follows pre-defined timing intervals controlled by a trimmed 32 kHz clock derived from the internal 16 MHz oscillator.
It integrates dedicated analog reference generation (VCOREREF, VCOREDIG, VCORE), isolated ground references (GNDREF1/GNDREF2/GNDREF), and fault-aware control logic-including open-drain INTB and RESETBMCU signals-with hardware-level PWRON assertion and SD_VSEL-driven VCC_SD voltage selection (1.80–1.85 V or 2.85–3.30 V). The VPWR front-end LDO option enables input operation up to 5.5 V using an external PMOS pass FET.
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 system supply compatibility and LDO activation path |
| SW1 output | 0.7–1.425 V, 1.8 V, or 3.3 V at 2.75 A; configured as 1.4 V default for i.MX 6UL ARM core rail |

| VSNVS output | 3.0 V at 1.0 mA; powers SNVS/SRTC domain and enables coin cell backup with integrated charger |
| VCC_SD output | 1.80–1.85 V or 2.85–3.30 V at 100 mA; selected dynamically via SD_VSEL pin for SD card interface compliance |
| I²C address | 0x08 (default); enables register-level configuration of DVS, fault masks, and regulator enable/disable states |
| Operating temperature | −40 °C to +105 °C; qualified for automotive applications per AEC-Q100 requirements |
Pinout & Package
MC33PF3001A7ESR2 uses a 48-pin QFN 7.0 mm × 7.0 mm wettable flank (WF-type) package (98ASA00933D), with exposed thermal pad (EP) tied to ground for enhanced thermal dissipation in automotive environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INTB | Open-drain interrupt output | Asserts low on fault events (e.g., overvoltage, thermal shutdown); requires external pull-up for MCU notification |
| RESETBMCU | Open-drain reset output | Deasserts 2.0 ms after final regulator enables; synchronizes processor exit from POR across full power tree |
| PWRON | Level-sensitive power-on input | Triggers startup sequence when high and VIN exceeds UVDET threshold; enables deterministic system wake-up |
| SD_VSEL | Digital select input | Configures VCC_SD output range: logic high → 1.80–1.85 V; logic low → 2.85–3.30 V for SDIO/SDMMC compliance |
| SCL / SDA | I²C interface pins | Enable runtime reconfiguration of regulator voltages, DVS slew rates, and fault interrupt masks (address 0x08) |
| VIN / VPWR | Main input / front-end LDO input | VIN used for ≤4.5 V supplies; VPWR enables >4.5 V operation via external PMOS (LDOG drives gate) |
| GNDREF1 / GNDREF2 / GNDREF | Isolated ground references | Separate return paths for SW1, SW2/SW3, and core logic prevent noise coupling into sensitive analog blocks |
| SW1LX / SW2LX / SW3LX | Buck switch node outputs | Connect directly to respective inductors; require tight layout with minimal trace inductance for EMI control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC34PF3001A7ESR2 | Same OTP configuration (A7), identical pinout and electrical specs, but rated for −40 °C to +105 °C industrial use instead of automotive qualification | Targets industrial automation and medical devices where AEC-Q100 is not required but extended temperature operation is needed | Select when automotive qualification is unnecessary and cost-sensitive industrial deployment is prioritized |
| MC33PF3001A6ESR2 | Shares same package and pinout; differs in OTP programming: supports i.MX 6UL with LPDDR2 (not DDR3L) and defaults SW1 to 1.4 V, SW2 to 3.3 V, SW3 to 1.2 V | Designed for legacy i.MX 6UL designs using LPDDR2 memory; incompatible with DDR3L timing and voltage requirements | Choose only for backward compatibility with existing LPDDR2-based i.MX 6UL platforms; not suitable for DDR3L systems |
Compared with MC33PF3001A7ESR2, MC34PF3001A7ESR2 offers identical functionality without automotive qualification, while MC33PF3001A6ESR2 targets different memory configurations-making both unsuitable as drop-in replacements unless matching the exact i.MX variant and memory type.

FAQ
What is the primary target processor for MC33PF3001A7ESR2?
MC33PF3001A7ESR2 is specifically programmed for the i.MX 6UL processor with DDR3L memory interface, as confirmed by its A7 OTP configuration (Table 4). Its default startup voltages-SW1 = 1.4 V (core), SW2 = 3.3 V (I/O), SW3 = 1.35 V (memory)-align precisely with i.MX 6UL DDR3L power requirements. It is not intended for i.MX 7 or i.MX 6SX variants without hardware and firmware validation.
Does MC33PF3001A7ESR2 support I²C reprogramming of output voltages?
Yes, MC33PF3001A7ESR2 supports full I²C-based reconfiguration of regulator output voltages via its 0x08 slave address. While OTP defines default startup values, registers like SW1VOLT[4:0] can be written during runtime to adjust SW1 between 0.7 V and 1.425 V in 25 mV steps, enabling dynamic voltage scaling for CPU performance tuning without hardware change.
How does the VSNVS rail function in MC33PF3001A7ESR2?
In MC33PF3001A7ESR2, the VSNVS rail delivers a fixed 3.0 V output at 1.0 mA to power the Secure Non-Volatile Storage (SNVS) and Real-Time Clock (RTC) domains of the i.MX 6UL. It operates from either VIN or an external coin cell connected to LICELL, with automatic switchover and integrated charging-ensuring continuous RTC operation during main power loss.
What is the role of the SD_VSEL pin on MC33PF3001A7ESR2?
The SD_VSEL pin on MC33PF3001A7ESR2 selects the output voltage range of the VCC_SD regulator: logic high configures 1.80–1.85 V for SDIO/SDMMC 1.8 V mode, while logic low sets 2.85–3.30 V for 3.3 V SD card operation. This hardware-selectable feature eliminates need for external level shifters or firmware-controlled LDO reconfiguration during SD interface initialization.
Can MC33PF3001A7ESR2 operate with a 5.0 V input supply?
Yes, MC33PF3001A7ESR2 supports 5.0 V input via the VPWR pin using the optional front-end LDO configuration. This requires populating an external PMOS pass FET (e.g., FDMA908PZ) and connecting VPWR to the 5.0 V rail; LDOG drives the FET gate, regulating VIN to ≤4.5 V. Direct 5.0 V connection to VIN is prohibited and will damage the IC.
