NXP Semiconductors MC34PF1510A1EPR2

Overview

MC34PF1510A1EPR2 from NXP Semiconductors is a power management IC (PMIC) engineered for i.MX 6UL/6ULL/7ULP application processors in low-power IoT, wearable, and embedded systems. It integrates three 1.0 A buck converters (SW1–SW3), three LDOs (LDO1–LDO3), VSNVS RTC supply (3.0 V/2.0 mA), DDR reference (VREFDDR: 0.5–0.9 V/10 mA), and I²C programmable control - delivering full-system power for processors, memory, and peripherals.

For engineers reviewing the MC34PF1510A1EPR2 datasheet, MC34PF1510A1EPR2 pinout, MC34PF1510A1EPR2 application, or MC34PF1510A1EPR2 equivalent, key selection criteria include its industrial −40 °C to 105 °C rating, OTP-configurable startup/power-down sequences, dynamic voltage scaling on SW1/SW2, and preprogrammed A1 configuration optimized for default i.MX 6UL/6ULL operation with DDR3L/LPDDR2 support.

Technical Context

The MC34PF1510A1EPR2 implements a multi-rail PMIC architecture with independent digital control logic, OTP-based configuration storage, and integrated front-end LDO (1500 mA, up to 6.5 V input). Its buck regulators use synchronous P/N-MOSFET topologies with programmable current limits (0.7–2.6 A), soft-start, and dual-mode operation (forced PWM or adaptive variable-frequency).

Regulator sequencing is managed by an internal state machine supporting Standby, Sleep/Low-power, and Off (REGS_DISABLE) modes. The device features dedicated USB_PHY LDO (4.9 V or 3.3 V/60 mA), always-on LDO2P7 (2.7 V/5.0 mA), coin cell charger interface (LICELL), and robust protection including overvoltage lockout (6.5 V), UVLO (4.0 V), thermal shutdown, and current limiting across all rails.

FAQ

What is the operating temperature range for the MC34PF1510A1EPR2?

The MC34PF1510A1EPR2 is rated for industrial ambient operation from −40 °C to 105 °C, as confirmed in Table 3 of the official datasheet. This specification applies to the MC34PF1510A1EPR2 variant with the "MC34" prefix, distinguishing it from consumer-grade MC32 variants limited to 85 °C. Thermal derating is required above 105 °C ambient per junction temperature limits.

Does the MC34PF1510A1EPR2 support dynamic voltage scaling?

Yes, the MC34PF1510A1EPR2 supports dynamic voltage scaling (DVS) on buck regulators SW1 and SW2, enabling real-time output voltage adjustment via I²C commands. DVS is configurable through OTP settings (OTP_SWx_DVS_SEL = 0) and operates across the 0.6 V to 1.3875 V range in 12.5 mV steps - critical for optimizing power consumption in i.MX processor DVFS implementations.

What is the purpose of the LICELL pin on the MC34PF1510A1EPR2?

The LICELL pin on the MC34PF1510A1EPR2 serves as a bidirectional coin cell interface: it accepts input from a 1.8–3.6 V coin cell for RTC backup and can also charge the cell from the VSYS rail when main power is present. The internal charger supports trickle charging with current limiting, and the pin requires a 0.1 µF bypass capacitor per datasheet Figure 4 and Table 2.

How is the MC34PF1510A1EPR2 configured for different i.MX processors?

The MC34PF1510A1EPR2 uses one-time programmable (OTP) memory to store configuration data including startup sequence, voltage levels, soft-start timing, and power-down behavior. As the "A1" variant, it implements the default configuration suitable for i.MX 6UL and 6ULL processors with LPDDR2 or DDR3L memory - distinct from A2/A3/A6 variants optimized for specific i.MX 7ULP or DDR3L timing requirements.

What package type and pin count does the MC34PF1510A1EPR2 use?

The MC34PF1510A1EPR2 uses a 40-pin QFN package measuring 5.0 mm × 5.0 mm with 0.5 mm pitch and an exposed thermal pad (EPAD). This package is documented in Table 1 of the datasheet as "98ASA00913D" and is shared across all MC34PF1510 variants, ensuring mechanical and thermal compatibility for drop-in replacement within the PF1510 family.
