Product details
Overview
MC32PF1550A3EPR2 from NXP Semiconductors is a preprogrammed power management IC (PMIC) optimized for i.MX 6UL processors with DDR3L memory, delivering three 1.0 A buck converters, three LDOs, RTC supply (VSNVS), DDR reference voltage (VREFDDR), and a linear Li-ion battery charger supporting 100–1000 mA charge current and JEITA-compliant thermal regulation. It operates across −40 °C to 105 °C in industrial environments.
For engineers reviewing the MC32PF1550A3EPR2 datasheet, MC32PF1550A3EPR2 pinout, MC32PF1550A3EPR2 application, or MC32PF1550A3EPR2 equivalent, key selection considerations include its OTP-configured startup sequence for i.MX 6UL/DDR3L, VSYS transient withstand up to +22 V, I²C-controlled dynamic voltage scaling on SW1/SW2, and integrated battery supplement mode with 3.0 A discharge overcurrent protection.
Technical Context
The MC32PF1550A3EPR2 implements a tightly integrated analog-digital PMIC architecture with dedicated regulators for core (VCORE), digital (VDIG), and system (VSYS) rails, plus independent feedback loops for SW1–SW3 buck converters-SW1 and SW2 support dynamic voltage scaling while SW3 delivers fixed 1.8–3.3 V outputs. Its internal 32 kHz and 16 MHz clocks synchronize regulator sequencing and watchdog timing.
Control logic resides in an OTP-programmable state machine that executes user-defined power-up/down sequences, standby/sleep/off modes, and event-driven responses via INTB and WDI interfaces. Battery management includes programmable CV/CC thresholds, thermistor-based JEITA compliance, and a 50 mΩ integrated isolation MOSFET enabling operation with no/low battery.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC34PF1550A3EPR2 | Identical functionality and pinout; differs only in extended temperature grade (−40 °C to 105 °C vs. −40 °C to 85 °C for MC32 variant) | Targeted at industrial-grade designs requiring full 105 °C operation; shares same i.MX 6UL/DDR3L OTP configuration | Select MC34PF1550A3EPR2 when ambient operating temperature exceeds 85 °C or industrial qualification is mandatory |
| PF8100A0EP | Higher integration: adds PMIC+audio codec; different buck/LDO count (4 buck, 6 LDO); no integrated battery charger | Designed for multimedia-rich i.MX 8M applications; lacks battery management but offers audio signal chain support | Choose PF8100A0EP only if audio subsystem integration is required and external battery charging is acceptable |
Compared with MC34PF1550A3EPR2, the MC32PF1550A3EPR2 offers identical power architecture and i.MX 6UL/DDR3L firmware but is rated for consumer-grade temperature range; versus PF8100A0EP, it trades audio capability for dedicated battery management and lower system BOM cost in resource-constrained IoT endpoints.

FAQ
What is the primary target processor for MC32PF1550A3EPR2?
The MC32PF1550A3EPR2 is preprogrammed for the i.MX 6UL application processor with DDR3L memory interface, as confirmed by its A3EP programming code in Table 1 of the PF1550 datasheet. Its OTP configuration defines startup sequencing, voltage rails, and timing parameters specifically aligned to i.MX 6UL power requirements.
Does MC32PF1550A3EPR2 support dynamic voltage scaling (DVS)?
Yes, MC32PF1550A3EPR2 supports DVS on buck converters SW1 and SW2, allowing real-time adjustment of output voltage under processor command via I²C. This feature enables adaptive power reduction for the i.MX 6UL core and digital domains during variable workload conditions.
What battery charging capabilities does MC32PF1550A3EPR2 provide?
MC32PF1550A3EPR2 integrates a linear Li-ion/Li-Po charger supporting 100–1000 mA programmable charge current, 3.5–4.44 V CV voltage, JEITA-compliant thermistor monitoring, and battery supplement mode. It includes a 50 mΩ integrated isolation MOSFET and 3.0 A discharge overcurrent protection.
Is MC32PF1550A3EPR2 compatible with i.MX 7ULP processors?
No-MC32PF1550A3EPR2 is specifically configured for i.MX 6UL with DDR3L, not i.MX 7ULP. The A2EP and A4EP variants in Table 1 are designated for i.MX 7ULP with LPDDR3; using MC32PF1550A3EPR2 with i.MX 7ULP would require reconfiguration unsupported by its OTP image.
What package type and thermal performance does MC32PF1550A3EPR2 use?
MC32PF1550A3EPR2 uses a 40-pin QFN package (5.0 mm × 5.0 mm, exposed pad). Its junction-to-ambient thermal resistance (RΘJA) is 17.8 °C/W on an eight-layer PCB, enabling reliable operation at full load within its −40 °C to 105 °C industrial temperature range.
