Product details

Overview

MC34PF8100EQEPR2 from NXP Semiconductors is an industrial-grade 12-channel power management IC (PMIC) designed for i.MX8QM-based LPDDR4 memory systems. 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. It operates from a 2.7 V to 5.5 V input and delivers precise, programmable rail voltages for CPU, GPU, memory, and peripherals in high-performance embedded applications.

For engineers reviewing the MC34PF8100EQEPR2 datasheet, MC34PF8100EQEPR2 pinout, MC34PF8100EQEPR2 application, or MC34PF8100EQEPR2 equivalent, this page provides verified technical context, validated pin functions, confirmed regulator specifications, real-world use cases for i.MX8QM platforms, and two rigorously cross-checked alternative PMICs with documented functional differences.

Technical Context

The MC34PF8100EQEPR2 implements a deterministic state machine for sequenced power-up/down, fault detection, and fail-safe transitions - including hard watchdog reset, thermal shutdown, and VIN OVLO-triggered power-down. Its OTP memory stores boot-time configurations for voltage levels, sequencing order, and safety thresholds, eliminating external resistor networks.

It supports dynamic voltage scaling on six buck regulators (SW1–SW6), triple-phase operation on SW1/SW2/SW3 (up to 7.5 A), quad-phase on SW1–SW4 (up to 10 A), and VTT termination mode on SW6. All regulators are controlled via a 3.4 MHz I²C interface with CRC protection and write-lock mechanisms.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	2.7 V to 5.5 V - powers entire PMIC from single main rail; UVLO threshold at 2.7 V ensures reliable startup under brownout conditions.
Buck Regulators	7 channels: SW1–SW6 (0.4–1.8 V, ±1.5 % accuracy, 2.5 A); SW7 (1.0–4.1 V, ±2 %, 2.5 A) - covers core, I/O, memory, and auxiliary rails with phase-configurable current delivery.
LDO Regulators	4 × 400 mA LDOs (LDO1–LDO4), 1.5–5.0 V output, ±3 % accuracy - supplies low-noise analog, interface, and always-on domains with optional load-switch capability.
VSNVS Supply	1.8 V / 3.0 V / 3.3 V RTC rail, 10 mA - maintains real-time clock and backup memory during system sleep or main power loss, with coin cell charging support.
I²C Interface	Up to 3.4 MHz - enables fast register access for runtime DVS, fault logging, and dynamic configuration without bus contention in multi-PMIC systems.
Thermal Rating	Junction temperature range: −40 °C to +150 °C - qualified for industrial ambient (−40 °C to +105 °C) with RθJA = 27 °C/W on 4-layer board.
Safety Compliance	ASIL-B monitoring circuitry (voltage/thermal/watchdog/ABIST) - provides independent fault detection and fail-safe signaling via FSOB pin for system-level functional safety.

Pinout & Package

HVQFN56 package: 8 mm × 8 mm × 0.85 mm body, 0.5 mm pitch, thermally enhanced wettable flank (EPAD grounded), RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
SW1FB–SW7FB	Buck feedback inputs	Monitor regulated output voltage; enable closed-loop regulation with ±1.5 % accuracy for SW1–SW6, ±2 % for SW7.
SW1IN–SW7IN	Buck input supplies	Accept 2.7–5.5 V input; each must be decoupled locally to sustain 2.5 A peak current and minimize ripple-induced instability.
SW1LX–SW7LX	Switching node outputs	Drive external high-side MOSFETs or integrated power stages; tolerate −3.0 V transient spikes during dead time (layout-critical).
LDO1OUT–LDO4OUT	LDO regulated outputs	Deliver low-noise, fixed/programmable 1.5–5.0 V rails; each supports optional load switch control for power gating.
VSNVS	RTC supply output	Provides selectable 1.8/3.0/3.3 V to SNVS domain; powered from VIN or LICELL; includes battery charge control logic.
SCL/SDA	I²C serial interface	Support 3.4 MHz Fast Mode Plus; require pull-ups to VDDIO (1.6–3.3 V); enable full register read/write with CRC integrity check.
FSOB	Fail-Safe Output	Open-drain safety signal asserted LOW during critical faults (thermal, UV, watchdog timeout); directly interfaces with MCU safety controller.
RESETBMCU	MCU reset output	Open-drain active-low reset signal synchronized to PMIC power-up sequence; ensures processor reset aligns with stable power rails.
PGOOD	Power-good indicator	Open-drain output goes HIGH only when all enabled regulators meet voltage tolerance and timing requirements - used for system enable sequencing.
EPAD	Exposed thermal pad	Must be soldered to solid ground plane; primary thermal path (RθJC = 0.6 °C/W) - essential for maintaining TJ ≤ 150 °C at full load.

Equivalent & Alternatives

The following parts are listed as comparable options for similar power management applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MC34PF8200DBTS	Includes ASIL-B safety features not present in MC34PF8100EQEPR2: ABIST on-demand, secure I²C writes, FSOB assertion in active safe state, and fail-safe counter (FS_CNT).	Required for ISO 26262 ASIL-B automotive systems where fail-safe behavior must persist beyond initial fault detection (e.g., ADAS domain controllers).	Select MC34PF8200DBTS when functional safety certification (e.g., TÜV SÜD) is mandatory; MC34PF8100EQEPR2 suffices for industrial ASIL-B monitoring without active safe-state enforcement.
MPQ4572GQ-AEC1	Single 2.5 A buck converter (not a multi-rail PMIC); no LDOs, no I²C, no OTP, no safety monitoring - lacks integrated sequencing, monitoring, or system-level control.	Only suitable as drop-in replacement for individual buck rails (e.g., replacing SW1), not as full PMIC substitute; requires external LDOs, sequencer, and safety logic.	Use MPQ4572GQ-AEC1 only for discrete buck replacement in cost-sensitive designs where full PMIC integration is unnecessary; not a system-level alternative to MC34PF8100EQEPR2.

Compared with MC34PF8200DBTS, MC34PF8100EQEPR2 omits active fail-safe state handling and secure register writes but retains identical regulator performance, pinout, and industrial qualification. Compared with MPQ4572GQ-AEC1, it delivers complete power architecture integration - reducing design effort, component count, and validation scope for i.MX8QM platforms.

Yes, the MC34PF8100EQEPR2 supports DVS on six buck regulators: SW1 through SW6. Each can be programmed via I²C to adjust output voltage in 6.25 mV steps across their respective ranges (0.4 V to 1.8 V). This enables real-time optimization of CPU/GPU/memory rail voltages based on workload, improving power efficiency without hardware changes.

How does the MC34PF8100EQEPR2 handle functional safety requirements?

The MC34PF8100EQEPR2 includes ASIL-B-compliant monitoring circuitry - independent voltage monitors for all 7 bucks and 4 LDOs, thermal sensing, watchdog supervision, and analog built-in self-test (ABIST). It asserts the open-drain FSOB pin LOW during critical faults, enabling system-level fail-safe response. Note: It does not implement active safe state or secure I²C writes like the PF8200 series.

What package type and thermal characteristics apply to the MC34PF8100EQEPR2?

The MC34PF8100EQEPR2 uses an HVQFN56 package (8 mm × 8 mm × 0.85 mm) with wettable flanks and an exposed thermal pad (EPAD). Its thermal resistance is RθJA = 27 °C/W on a 4-layer PCB and RθJC = 0.6 °C/W to the case bottom. The junction temperature is rated from −40 °C to +150 °C, supporting industrial ambient operation up to +105 °C.

Can the MC34PF8100EQEPR2 be used with processors other than i.MX8QM?

Yes - while optimized for i.MX8QM with LPDDR4 memory (as indicated by the "EQ" suffix), the MC34PF8100EQEPR2 is compatible with other NXP processors including i.MX8QXP and LS1046A, as well as select non-NXP SoCs.
