Product details

Overview

MC34PF8100FJEPR2 from NXP Semiconductors is an industrial-grade 12-channel power management IC (PMIC) designed for i.MX 8QXP processors with LPDDR4 memory. It integrates seven high-efficiency buck converters (0.4–1.8 V, 2.5 A each), four 400 mA LDOs, RTC supply (VSNVS), coin cell charger, watchdog timer, and ASIL B-compliant monitoring circuitry. It supports dynamic voltage scaling, dual/triple/quad-phase configurations, and operates from a 2.7–5.5 V input.

For engineers reviewing the MC34PF8100FJEPR2 datasheet, MC34PF8100FJEPR2 pinout, MC34PF8100FJEPR2 application, or MC34PF8100FJEPR2 equivalent, key selection considerations include its OTP-programmable startup sequence, 3.4 MHz I²C interface, 56-pin HVQFN package with wettable flanks, thermal shutdown protection, and support for automotive-qualified i.MX 8QXP systems in industrial environments.

Technical Context

The MC34PF8100FJEPR2 implements a deterministic state machine for seamless i.MX 8QXP boot coordination, including programmable soft-start/power-down sequencing, fault detection (OV/UV, thermal, watchdog timeout), and fail-safe transitions. Its 24-channel analog multiplexer enables real-time system diagnostics across all regulator outputs and critical nodes.

It features hardware-configurable regulator grouping: SW1/SW2 (dual-phase), SW3/SW4 (dual-phase), SW5/SW6 (dual-phase), and SW1–SW4 (quad-phase up to 10 A), plus SW7 as an independent 1.0–4.1 V, 2.5 A buck. The VTT termination mode on SW6 supports DDR memory interfaces, while VSNVS provides selectable 1.8/3.0/3.3 V RTC backup from VIN or coin cell.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	2.7 V to 5.5 V - powers entire PMIC from single 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), SW7 (1.0–4.1 V, ±2% accuracy) - supports core, I/O, memory, and peripheral rails of i.MX 8QXP with tight regulation.
LDO Regulators	4 × 400 mA LDOs (1.5–5.0 V, ±3% accuracy) with optional load switch mode - delivers low-noise analog/IO supplies and flexible power gating.
I²C Interface	Up to 3.4 MHz - enables fast post-boot configuration and dynamic voltage scaling during runtime without interrupting processor operation.
Package	HVQFN56, 8 mm × 8 mm × 0.85 mm, 0.5 mm pitch, wettable flanks - optimized for thermal dissipation and automated optical inspection (AOI) in industrial PCB assembly.
Operating Temperature	−40 °C to +105 °C ambient - qualified for extended industrial environments with junction limit of 150 °C and thermal resistance RθJA = 27 °C/W (4-layer board).
Safety Monitoring	ASIL B-compliant monitoring: independent voltage monitors, thermal shutdown, ABIST, CRC-protected registers - meets functional safety requirements for non-automotive industrial control systems.

Pinout & Package

HVQFN56 package (SOT684-21), 8 mm × 8 mm × 0.85 mm body, thermally enhanced with exposed EPAD connected to ground. Wettable flank design enables reliable solder joint inspection.

Pin/Terminal	Circuit Role	Design Meaning
1	DNC1	Do not connect - no internal connection; must remain floating per layout guidelines.
2–3, 12–13, 30–31, 38	SWxFB	Buck feedback inputs - monitor regulated output voltage for closed-loop control; require external resistor dividers for programming.
4–7, 8–11, 32, 35, 37	SWxIN	Buck input supplies - accept 2.7–5.5 V input; must be decoupled locally to minimize noise and ripple.
5–6, 9–10, 33–34, 36	SWxLX	Switching node outputs - high-frequency AC nodes connecting to external inductors; require tight layout and low-inductance paths.
15, 18, 25, 28	LDOxOUT	LDO regulated outputs - deliver stable 1.5–5.0 V, 400 mA supplies with low dropout and minimal PSRR degradation.
17, 26–27, 46	LDOxIN / LICELL	Input supplies - LDO12IN powers LDO1/LDO2; LDO3IN/LDO4IN are independent; LICELL accepts 0–4.2 V coin cell for RTC backup.
40–41	V1P5D / V1P5A	Digital/analog 1.5 V core supplies - dedicated low-noise outputs for i.MX 8QXP's internal logic and analog blocks.

55–56	SCL / SDA	I²C bus interface - supports standard/fast/high-speed modes up to 3.4 MHz; requires pull-up resistors to VDDIO (1.6–3.3 V).
50	VIN	Main input supply - primary 2.7–5.5 V source for all internal regulators; must be heavily decoupled near pin.
45, 51, 57	DGND / AGND / EPAD	Ground references - separate digital/analog grounds reduce noise coupling; EPAD must be soldered to large PCB ground plane for thermal and EMI performance.

Key Features

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MC34PF8200FJEP	Includes ASIL B safety features (ABIST, FSOB assertion logic, secure I²C write) absent in MC34PF8100FJEPR2; identical pinout and electrical specs.	Required for ISO 26262 ASIL B-certified automotive systems; not needed for industrial QM-grade applications.	Select MC34PF8200FJEP only if functional safety certification is mandated; otherwise MC34PF8100FJEPR2 offers lower cost and simpler configuration.
MPQ4436-AEC1	Single 3.5 A buck converter (no PMIC integration); lacks LDOs, OTP, I²C, safety monitoring, or multi-rail sequencing capability.	Only suitable as replacement for individual buck rails (e.g., SW7), not as full PMIC substitute.	Not a system-level alternative; use only for discrete rail replacement where full PMIC functionality is unnecessary.

Compared with MC34PF8200FJEP, MC34PF8100FJEPR2 omits safety-critical ABIST and fail-safe state logic but retains identical power delivery performance and industrial temperature range; MPQ4436-AEC1 serves only as a point-replacement buck, lacking any PMIC-level integration or sequencing.

FAQ

What is the input voltage range supported by the MC34PF8100FJEPR2?

The MC34PF8100FJEPR2 supports a main input voltage range of 2.7 V to 5.5 V on the VIN pin. This range accommodates common industrial and automotive pre-regulated supplies. Input voltages below 2.7 V trigger undervoltage lockout (UVLO), preventing unreliable operation. Absolute maximum rating is 6.0 V, but sustained operation above 5.5 V is limited to ≤1800 seconds over device lifetime per datasheet specification.

Does the MC34PF8100FJEPR2 support dynamic voltage scaling (DVS) for its buck regulators?

Yes, the MC34PF8100FJEPR2 supports dynamic voltage scaling on SW1 through SW6 via its 3.4 MHz I²C interface. Each buck can be reconfigured in real time for voltage and current limits, enabling adaptive power management during processor DVFS transitions. SW7 does not support DVS due to its fixed 1.0–4.1 V range and ±2% accuracy specification.

How is the RTC supply (VSNVS) configured on the MC34PF8100FJEPR2?

The MC34PF8100FJEPR2 provides VSNVS as a selectable 1.8 V, 3.0 V, or 3.3 V output capable of delivering 10 mA. It is powered either from the main VIN supply or from an external coin cell connected to the LICELL pin (0–4.2 V). The device includes a programmable coin cell charger with adjustable charge current and voltage, ensuring reliable RTC operation during main power loss.

What safety features does the MC34PF8100FJEPR2 include, and how do they differ from the PF8200 family?

The MC34PF8100FJEPR2 includes ASIL B-compliant monitoring circuits (voltage, thermal, watchdog), PGOOD signaling, and early warning (EWARNB) - meeting QM safety grade requirements. Unlike the PF8200, it lacks ABIST-on-demand, fail-safe state locking (FSOB assertion logic), secure I²C write, and CRC-protected mirror registers, which are exclusive to ASIL B-certified PF8200 variants.

Can the MC34PF8100FJEPR2 be used with processors other than i.MX 8QXP?

Yes, the MC34PF8100FJEPR2 is compatible with other NXP processors including i.MX 8QM and select i.MX 6 series devices, as well as certain non-NXP high-performance SoCs. Its 7-buck + 4-LDO architecture, programmable sequencing, and wide output voltage ranges provide flexibility beyond i.MX 8QXP, though OTP configuration files and reference designs are optimized for NXP platforms.
