Product details
Overview
MC33PF3000A7ESR2 from NXP Semiconductors is a power management IC (PMIC) engineered for i.MX 6UL application processors with DDR3L memory, delivering four buck regulators (SW1A: 1.0 A, SW1B: 1.75 A, SW2: 1.25 A, SW3: 1.5 A), six LDOs, VREFDDR reference, and coin-cell charging. It operates across −40 °C to +105 °C and supports dynamic voltage scaling for ARM core and SOC logic rails in automotive-grade embedded systems.
For engineers reviewing the MC33PF3000A7ESR2 datasheet, MC33PF3000A7ESR2 pinout, MC33PF3000A7ESR2 application, or MC33PF3000A7ESR2 equivalent, key selection criteria include its OTP-programmable startup sequence, I²C-configurable regulator voltages, VPWR front-end LDO support for >4.5 V inputs, and dedicated VSNVS 3.0 V always-on rail for secure real-time clock operation.
Technical Context
The MC33PF3000A7ESR2 integrates SMARTMOS technology and uses OTP memory to store startup configuration-including regulator output voltages, sequencing order, PWRON edge/level mode, and I²C slave address-eliminating external configuration components. Its control logic enables direct hardware interfacing via STANDBY, RESETBMCU, INTB, and SD_VSEL pins alongside I²C register access.
It supports dual-mode buck operation: SW1A and SW1B can run independently (1.0 A / 1.75 A) or combine into a single 2.75 A channel. The VREFDDR output tracks 50% of SW3's output voltage, enabling precise DDR3L termination, while VSNVS functions as either an LDO or bypass switch powered by VIN or coin cell.

| VSNVS | Always-on RTC supply | 3.0 V output; powers i.MX 6UL's secure non-volatile storage and real-time clock during deep sleep |
| PWRON | Power-on control input | Configurable edge- or level-sensitive; debounced (31.25–750 ms) for mechanical switch interface |
| SD_VSEL | VCC_SD voltage select | Digital input setting VCC_SD to 1.80–1.85 V (SD_VSEL=1) or 2.85–3.30 V (SD_VSEL=0) for SD card I/O |

FAQ
What is the operating temperature range of the MC33PF3000A7ESR2?
The MC33PF3000A7ESR2 is rated for −40 °C to +105 °C and qualified per AEC-Q100 Grade 2, making it suitable for automotive under-hood and infotainment applications where extended thermal performance is required. This rating is confirmed in Table 1 of the PF3000 datasheet and applies specifically to the MC33PF3000A7ESR2 variant.
Does the MC33PF3000A7ESR2 support DDR3L memory interfaces?
Yes, the MC33PF3000A7ESR2 supports DDR3L through its dedicated VREFDDR output, which tracks 50% of the SW3 buck regulator voltage with ±1% accuracy and 10 mA drive capability. Its OTP programming includes preset configurations for i.MX 6UL with DDR3L, as indicated by programming option "7" in the ordering table.
How is the VCC_SD output voltage selected on the MC33PF3000A7ESR2?
The VCC_SD output voltage on the MC33PF3000A7ESR2 is selected dynamically via the SD_VSEL pin: logic high sets 1.80–1.85 V for high-speed SD card operation, while logic low selects 2.85–3.30 V for standard SD I/O. The SD_VSEL buffer is powered by VDDIO, and defaults to high if VDDIO is absent.
Can the MC33PF3000A7ESR2 operate with a 5 V input supply?
Yes, the MC33PF3000A7ESR2 supports 3.7–5.5 V input via the VPWR pin when used with an external P-MOSFET front-end LDO. This configuration limits internal regulator input to ≤4.5 V, protecting the device. Direct 5 V connection to VIN is not permitted - only VPWR with external FET enables safe 5 V operation.
What is the purpose of the LICELL pin on the MC33PF3000A7ESR2?
The LICELL pin on the MC33PF3000A7ESR2 provides bidirectional coin-cell interface: it charges a connected coin cell during main power operation and supplies VSNVS during main power loss. It supports automatic switchover and includes charge current limiting, enabling secure RTC and SNVS domain retention without external charging circuitry.
