Product details
Overview
MC32PF3000A5EPR2 from NXP Semiconductors is a power management IC (PMIC) engineered for i.MX 6SL application processors with LPDDR2 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 from 2.8–4.5 V input, supports dynamic voltage scaling, and integrates OTP-programmable startup sequencing for embedded system power trees.
For engineers reviewing the MC32PF3000A5EPR2 datasheet, MC32PF3000A5EPR2 pinout, MC32PF3000A5EPR2 application, or MC32PF3000A5EPR2 equivalent, this page provides verified regulator configurations, I²C-address programmability, thermal-aware 48-QFN wettable flank package details, and validated alternatives for i.MX 6SL-based industrial and consumer designs.
Technical Context
The MC32PF3000A5EPR2 implements SMARTMOS technology to integrate four synchronous buck converters-SW1A/B configurable as independent or combined 2.75 A channel-with programmable soft-start ramp rates (25 mV/2 µs or 4 µs), PWM/PPM/APSM modes, and dynamic voltage scaling for core rail control. Its dedicated VREFDDR (0.5 × SW3_OUT, 10 mA) and VSNVS (3.0 V, 1.0 mA) blocks directly support i.MX 6SL's SNVS domain and DDR2/LPDDR2 reference requirements.
Control logic includes OTP-configurable PWRON edge/level detection, STANDBY polarity inversion, RESETBMCU fault-mode timing (1.8 ms fault hold), and I²C slave address selection (0x08–0x0F). All seven LDOs-including VCC_SD (dual-range 1.8 V / 2.85–3.3 V, 100 mA) and V33 (2.85–3.3 V, 350 mA)-are sequenced via 3- or 4-bit OTP startup slots with 0.5/2.0 ms inter-slot delays.

FAQ
What is the input voltage range supported by the MC32PF3000A5EPR2?
The MC32PF3000A5EPR2 supports an input voltage range of 2.8 V to 4.5 V when powered through the VIN pin. For systems with input voltages up to 5.5 V, the VPWR pin can be used with an external P-MOSFET to implement a front-end LDO-ensuring internal regulator inputs remain within safe limits. This dual-input architecture makes MC32PF3000A5EPR2 compatible with both single-cell Li-ion and USB-powered designs.
How does the MC32PF3000A5EPR2 support i.MX 6SL with LPDDR2 memory?
The MC32PF3000A5EPR2 is pre-programmed (OTP code A5) to match the i.MX 6SL + LPDDR2 power tree: SW3 delivers 0.9 V–1.35 V core voltage, VREFDDR provides 0.5 × SW3_OUT (e.g., 0.675 V) for LPDDR2 termination, and VSNVS supplies 3.0 V to the i.MX 6SL's SNVS domain. Its startup sequence ensures VREFDDR stabilizes before LPDDR2 initialization begins-critical for reliable memory training.
Can the MC32PF3000A5EPR2 be reconfigured after soldering?
No-OTP memory in the MC32PF3000A5EPR2 is one-time programmable and cannot be rewritten. However, runtime configuration is fully supported via its I²C interface: output voltages, DVS transitions, regulator enable/disable states, and interrupt masking can all be modified dynamically. The OTP defines only the cold-start behavior; all operational parameters remain software-controllable post-power-up.
What is the purpose of the SD_VSEL pin on the MC32PF3000A5EPR2?
The SD_VSEL pin on the MC32PF3000A5EPR2 selects between two output voltage ranges for the VCC_SD LDO: logic-high sets 1.8 V (for UHS-I SD cards), while logic-low sets 2.85–3.3 V (for legacy SD/SDIO). This hardware-selectable dual-voltage capability eliminates external level shifters and simplifies board design for devices supporting multiple SD card standards.
Does the MC32PF3000A5EPR2 include battery backup functionality?
Yes-the MC32PF3000A5EPR2 integrates a dedicated coin-cell charger and VSNVS (3.0 V, 1.0 mA) regulator that remains active in all low-power states. When a coin cell is connected to LICELL, it autonomously charges the cell and supplies the i.MX 6SL's Secure Non-Volatile Storage domain-preserving RTC time, cryptographic keys, and boot state during main power loss.
