Product details
Overview
MC34PF8100FJEP from NXP Semiconductors is an industrial-grade 12-channel power management IC (PMIC) designed for i.MX8QXP application processors with LPDDR4 memory subsystems. It integrates seven high-efficiency buck converters (SW1–SW7), four 400 mA LDOs (LDO1–LDO4), RTC supply (VSNVS), coin cell charger, watchdog timer, and ASIL-B-compliant monitoring circuitry. Its OTP-configurable startup sequence and 3.4 MHz I²C interface enable precise, flexible power sequencing in high-performance embedded systems.
For engineers reviewing the MC34PF8100FJEP datasheet, MC34PF8100FJEP pinout, MC34PF8100FJEP application, or MC34PF8100FJEP equivalent, key selection considerations include its 56-pin HVQFN package, dual-phase and triple-phase buck configuration capability, VTT termination on SW6, programmable soft-start/power-down sequences, and thermal shutdown protection up to 150 °C junction temperature.
Technical Context
The MC34PF8100FJEP implements a deterministic state machine for fault-aware power-up, runtime monitoring, and fail-safe transitions - including hard watchdog reset, critical failure shutdown, and standby-to-run control via STANDBY/STANDBYINV logic. Its safety architecture includes independent voltage monitors, thermal sensors, ABIST, and PGOOD signaling but excludes PF8200-specific features like FSOB-assisted safe state assertion or secure I²C writes.
It supports dynamic voltage scaling across six primary bucks (SW1–SW6), configurable as dual-, triple-, or quad-phase regulators (up to 10 A total), while SW7 operates independently at 1.0–4.1 V. All bucks feature spread-spectrum modulation, manual frequency tuning, and programmable current limits; LDOs support optional load-switch mode and hardware/software enable control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Regulator Count | 7 buck converters + 4 LDOs + VSNVS RTC supply + coin cell charger - fully integrated power tree for i.MX8QXP with LPDDR4. |
| Buck Output Range | SW1–SW6: 0.4–1.8 V (6.25 mV steps); SW7: 1.0–4.1 V - covers CPU core, GPU, memory I/O, and peripheral rails. |
| Current Rating | 2500 mA per buck; 400 mA per LDO - sufficient for LPDDR4 VDDQ/VTT and processor core domains. |
| I²C Interface | Up to 3.4 MHz - enables fast post-boot reconfiguration of voltage, sequencing, and protection thresholds. |
| Operating Temp | −40 °C to +105 °C ambient - qualified for industrial environments without derating. |

Pinout & Package
HVQFN56 package with exposed thermal pad (EPAD), 0.5 mm pitch, 8 mm × 8 mm body, 0.85 mm height, non-wettable flank (EP suffix). EPAD must be connected to ground for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW1FB–SW7FB | Buck output voltage feedback | Enables closed-loop regulation; supports external resistor dividers for precise output setting. |
| SW1IN–SW7IN | Buck input supply | Accepts 2.7–5.5 V input; SW1–SW6 share common VIN domain; SW7 may use separate rail. |
| SW1LX–SW7LX | Buck switching node | High-frequency switching output; requires low-inductance layout and proper snubbing for EMI control. |

| VSNVS | RTC supply output | 1.8/3.0/3.3 V selectable, 10 mA - powers SNVS domain and retains real-time clock during system sleep. |
| SCL/SDA | I²C interface | 3.4 MHz capable; supports register read/write, OTP programming, and real-time monitoring via host MCU. |
| PGOOD/INTB/RESETBMCU | Status and control signals | Open-drain outputs for system-level power-good indication, interrupt signaling, and MCU reset coordination. |
| VIN/VDDIO/DGND/AGND/EPAD | Power and ground | VIN: main 2.7–5.5 V input; VDDIO: 1.6–3.3 V I/O supply; DGND/AGND/EPAD require separate low-impedance ground planes. |
Key Features
| Feature | Design Value |
|---|---|
| OTP-based startup configuration | Eliminates external resistors and sequencers; stores voltage targets, timing, and enable order for repeatable boot behavior. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC34PF8200DEEP | Includes ASIL-B FSOB fail-safe output, secure I²C, ABIST-on-demand, and enhanced watchdog state machine - not present in MC34PF8100FJEP. | Required for automotive infotainment where fail-safe assertion and certified safety mechanisms are mandatory. | Select MC34PF8200DEEP only if ASIL-B certification, FSOB-driven system shutdown, or secure register write protection are required. |
| MPQ4572GQ-AEC1 | Single 2.5 A buck regulator (no LDOs, no OTP, no I²C, no safety monitoring) - discrete replacement for one rail only. | Used for cost-sensitive, non-safety-critical auxiliary rails where full PMIC integration is unnecessary. | Choose MPQ4572GQ-AEC1 only as a drop-in buck for replacing SW7 or a single LDO; cannot substitute MC34PF8100FJEP's full functionality. |
Compared with MC34PF8200DEEP, MC34PF8100FJEP offers identical buck/LDO performance and industrial qualification but omits automotive safety features; compared with MPQ4572GQ-AEC1, it provides complete system power management with sequencing, monitoring, and configurability - eliminating need for 11 discrete regulators.

FAQ
What is the input voltage range supported by the MC34PF8100FJEP?
The MC34PF8100FJEP accepts a main input voltage (VIN) from 2.7 V to 5.5 V. Buck regulator inputs (SWxIN) and LDO inputs (LDOxIN) also operate within −0.3 V to 6.0 V absolute maximum, but recommended operating range remains 2.7–5.5 V to ensure reliability and avoid extended overvoltage stress. The LICELL pin supports up to 4.2 V for coin cell backup.
Does the MC34PF8100FJEP support dynamic voltage scaling (DVS)?
Yes, the MC34PF8100FJEP supports DVS on SW1 through SW6. Each of these bucks can be reconfigured in real time via I²C to adjust output voltage in 6.25 mV steps across their full range (0.4–1.8 V), enabling adaptive power management for CPU/GPU frequency scaling in i.MX8QXP-based systems.
How does the MC34PF8100FJEP handle power sequencing during startup?
The MC34PF8100FJEP uses one-time programmable (OTP) memory to store a fixed, deterministic power-up sequence - including enable timing, voltage targets, and inter-rail dependencies. This eliminates external sequencing components and ensures repeatable, glitch-free boot for i.MX8QXP processors with LPDDR4 memory.
Is the MC34PF8100FJEP pin-compatible with the MC33PF8100FJES automotive variant?
Yes, the MC34PF8100FJEP and MC33PF8100FJES share identical HVQFN56 pinout, electrical characteristics, and functional block diagram. The key difference is qualification grade: MC34PF8100FJEP is industrial (−40 °C to +105 °C), while MC33PF8100FJES is automotive AEC-Q100 Grade 2 (−40 °C to +105 °C) with QM safety status.
What safety features are implemented in the MC34PF8100FJEP?
The MC34PF8100FJEP includes ASIL-B-compliant monitoring: independent voltage monitors for all rails, thermal shutdown at 150 °C, watchdog timer with programmable timeout, PGOOD assertion, and analog built-in self-test (ABIST). It lacks PF8200-specific fail-safe outputs (FSOB) and secure I²C, confirming its industrial - not automotive safety-certified - role.
