Product details
Overview
MC32PF1510A7EPR2 from NXP Semiconductors is a power management IC (PMIC) engineered for i.MX 6UL application processors in consumer-grade IoT and wearable devices. It integrates three 1.0 A buck converters (SW1–SW3), three LDOs (LDO1–LDO3), DDR reference (VREFDDR), RTC supply (VSNVS), and I²C programmable control. Its −40 °C to +85 °C operating range and OTP-configurable startup sequence support low-power portable systems.
For engineers reviewing the MC32PF1510A7EPR2 datasheet, MC32PF1510A7EPR2 pinout, MC32PF1510A7EPR2 application, or MC32PF1510A7EPR2 equivalent, key selection criteria include its preprogrammed configuration for i.MX 6UL with LPDDR2 memory, 40-pin QFN package with exposed thermal pad, and support for dynamic voltage scaling on SW1/SW2 with <1.0 µA quiescent current in ULP mode.
Technical Context
The MC32PF1510A7EPR2 implements a front-end LDO (1500 mA input limit, up to 6.5 V operation) feeding three synchronous buck regulators with internal digital soft-start and adaptive variable-frequency or forced PWM modes. Its OTP memory stores device-specific startup/power-down sequences, regulator voltages, and DVS settings tailored for i.MX 6UL + LPDDR2 system requirements.
It delivers precise analog core (VCORE) and digital core (VDIG) supplies, supports coin-cell backup via LICELL, provides USB PHY LDO (4.9 V or 3.3 V, 60 mA), and includes dedicated always-on LDO2P7 (2.7 V, 5 mA) and RTC rail (VSNVS, 3.0 V, 2.0 mA) - all coordinated through an I²C interface with interrupt (INTB) and reset (RESETBMCU) signaling.
