Product details
Overview
MC32PF1550A0EP from NXP Semiconductors is a preprogrammed power management IC (PMIC) engineered for i.MX 6UL/6ULL/6SX/7ULP application processors in battery-powered IoT and wearable systems. It integrates three 1.0 A buck converters (SW1–SW3), three LDOs (LDO1–LDO3), RTC supply (VSNVS), DDR reference (VREFDDR), and a linear Li-ion charger supporting 100–1000 mA charge current with JEITA-compliant thermal regulation.
For engineers reviewing the MC32PF1550A0EP datasheet, MC32PF1550A0EP pinout, MC32PF1550A0EP application, or MC32PF1550A0EP equivalent, this page delivers verified specifications, validated pin functions, confirmed i.MX processor compatibility, and real-world use cases for low-power embedded designs requiring integrated power sequencing and battery management.
Technical Context
The MC32PF1550A0EP implements a multi-rail PMIC architecture with independent programmable control of SW1 and SW2 via I²C for dynamic voltage scaling (DVS), while SW3 operates at fixed 1.8–3.3 V outputs. Its integrated linear charger supports USB PHY LDO, coin-cell backup, and battery supplement mode with VSYS transient tolerance up to +22 V DC.
Internal OTP memory stores startup/power-down sequences, regulator voltages, and charger parameters. The device operates across −40 °C to 105 °C and features watchdog timer (80 s period), thermistor-based JEITA battery monitoring, and battery overcurrent protection configurable from 2.0 A to 4.0 A.
