Product details
Overview
MC34PF1510A4EPR2 from NXP Semiconductors is a preprogrammed power management IC (PMIC) optimized for i.MX 7ULP processors with LPDDR3 memory in industrial-grade applications. It integrates three 1.0 A buck converters, three LDOs (including USB_PHY and always-on LDO2P7), DDR reference (VREFDDR), RTC supply (VSNVS), coin-cell charger, and OTP-configurable power sequencing. It operates across −40 °C to 105 °C and supports dynamic voltage scaling on SW1/SW2 for ultra-low-power wearable and IoT edge devices.
For engineers reviewing the MC34PF1510A4EPR2 datasheet, MC34PF1510A4EPR2 pinout, MC34PF1510A4EPR2 application, or MC34PF1510A4EPR2 equivalent, key selection considerations include its factory-programmed startup sequence for i.MX 7ULP + LPDDR3, 40-pin QFN package with exposed thermal pad, I²C programmability, and industrial temperature rating - critical for reliable deployment in smart sensors, embedded monitoring, and industrial IoT gateways.
Technical Context
The MC34PF1510A4EPR2 implements a tightly integrated analog-digital PMIC architecture with dedicated front-end LDO (1500 mA, up to 6.5 V input), three synchronous buck regulators (SW1/SW2 with DVS and variable-frequency operation; SW3 fixed 1.8–3.3 V), and five configurable LDOs. Its OTP memory stores device-specific power-up/down timing, voltage levels, and soft-start parameters validated for i.MX 7ULP boot requirements.
Control logic includes I²C interface (1.7–3.6 V VDDIO), watchdog timer (80 s period), open-drain interrupt (INTB) and reset (RESETBMCU), standby/ONKEY inputs, and hardware-based power state management (Standby, Sleep/Low-power, Off). All regulators feature current limiting, soft start, and thermal protection within a single 5.0 mm × 5.0 mm QFN package.

Pinout & Package
MC34PF1510A4EPR2 uses a 40-pin QFN package (98ASA00913D) with 5.0 mm × 5.0 mm footprint and exposed EPAD for thermal grounding. Pin numbering follows standard top-view orientation per Figure 4 of the datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (WDI) | Watchdog input | Accepts processor watchdog pulse; pull-up required if unused - ensures system-level fault recovery |
| 2–3 (SDA/SCL) | I²C bidirectional bus | Configures regulators, monitors status, reads OTP settings; requires VDDIO pull-ups - enables runtime power policy updates |
| 6 (PWRON) | Power-on request | Initiates PMIC startup sequence when asserted by processor - synchronizes SoC boot with regulated rail ramp-up |
| 9 (INTB) | Open-drain interrupt | Signals fault conditions (OV/UV, thermal, watchdog timeout); pull-up to VSNVS required - provides real-time system health feedback |
| 11–12 (VLDO3IN/VLDO3) | LDO3 input/output | Supplies 300 mA at programmable voltage; bypassed with 4.7 µF capacitor - powers auxiliary peripherals with low-noise regulation |
| 25–27 (SW1LX/SW1IN/SW1FB) | Buck 1 switching node, input, feedback | Drives 1.0 A core rail; FB connects near load for accuracy; LX routes to external inductor - forms complete DC-DC stage with minimal external components |
| 30 (VSNVS) | RTC supply output | Delivers 3.0 V / 2.0 mA with coin-cell backup support - maintains real-time clock during main power loss |
| 35–36 (VSYS) | Main PMIC input rail | Dual VSYS pins accept 2.5–4.5 V from front-end LDO; bypassed with 47 µF capacitor - supplies all internal regulators |
| 37 (VIN) | Main IC supply input | Accepts 5.0 V adapter/USB source; bypassed with 2.2 µF capacitor - feeds front-end LDO and enables wide-input flexibility |
| 38 (LDO2P7) | Always-on 2.7 V regulator | Provides 5 mA at 2.7 V; mandatory 2.2 µF bypass - powers critical logic (e.g., RTC control, wake-up circuitry) continuously |
| 41 (EPAD) | Exposed thermal pad | Functions as ground return for buck regulators; must connect to inner/outer ground planes via multiple vias - ensures thermal reliability at full load |

FAQ
What is the primary target processor for MC34PF1510A4EPR2?
The MC34PF1510A4EPR2 is factory-programmed for the i.MX 7ULP application processor with LPDDR3 memory interface. Its OTP configuration includes optimized power-up sequencing, voltage levels, and timing parameters validated specifically for this SoC family - ensuring reliable boot and operation without external configuration.
Does MC34PF1510A4EPR2 support dynamic voltage scaling (DVS)?
Yes, MC34PF1510A4EPR2 supports DVS on buck regulators SW1 and SW2, enabling real-time adjustment of output voltage in 12.5 mV steps during operation. This feature is used to reduce dynamic power consumption in ARM core clusters and is fully functional in both normal and low-power modes per the datasheet specifications.
What is the maximum input voltage MC34PF1510A4EPR2 can withstand?
MC34PF1510A4EPR2 VIN pin withstands transient and DC inputs from 0 V up to +22 V, with an operating input voltage range of 4.1 V to 6.0 V. This robustness allows direct connection to unregulated 5 V USB or adapter sources without external overvoltage protection circuitry.
How does MC34PF1510A4EPR2 handle RTC backup power?
MC34PF1510A4EPR2 provides RTC backup via the VSNVS output (3.0 V / 2.0 mA) and integrated coin-cell charger on the LICELL pin. When main power fails, VSNVS maintains RTC operation using energy from an optional coin cell, ensuring timekeeping continuity and secure boot integrity across power cycles.
Is MC34PF1510A4EPR2 pin-compatible with other PF1510 variants?
Yes, all PF1510 variants including MC34PF1510A4EPR2 share identical 40-pin QFN packaging, pinout, and electrical interface. Differences exist only in OTP programming (startup sequence, voltage targets, memory interface support), so hardware design reuse is fully supported across the family - software/firmware must match the specific variant's configuration.
