Product details
Overview
MC34PF8100EPEP from NXP Semiconductors is an industrial-grade 12-channel power management IC (PMIC) designed as the primary power solution for i.MX8QM processors with LPDDR4 memory (PMIC1 role). 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–compatible monitoring circuitry. It operates from a 2.7–5.5 V input and supports dynamic voltage scaling across six buck channels.
For engineers reviewing the MC34PF8100EPEP datasheet, MC34PF8100EPEP pinout, MC34PF8100EPEP application, or MC34PF8100EPEP equivalent, this page delivers verified technical context, validated pin functions, confirmed regulator specifications, real-world automotive/industrial use cases, and two rigorously cross-checked alternative PMICs - all grounded in NXP's PF8100/PF8200 Rev. 13 product data sheet.
Technical Context
The MC34PF8100EPEP implements a deterministic state machine for seamless i.MX8QM boot sequencing, fault detection, and fail-safe transitions - including programmable soft-start/power-down sequences, PGOOD monitoring, and thermal shutdown at 150 °C. Its architecture supports multi-phase configurations: SW1/SW2 as dual-phase (5 A), SW3/SW4 as dual-phase (5 A), SW5/SW6 as dual-phase (5 A), and SW1/SW2/SW3 as triple-phase (7.5 A).
It features OTP-based startup configuration storage, 3.4 MHz I²C interface with CRC protection, 24-channel analog multiplexer for system diagnostics, and independent voltage monitors with programmable thresholds. Unlike the PF8200, it lacks ABIST-on-demand, secure I²C write, and fail-safe output (FSOB) assertion logic - confirming its industrial QM safety grade per Table 2.
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 each); SW7 (1.0–4.1 V, ±2 %, 2.5 A) - enables full-core, GPU, memory, and I/O rail regulation for i.MX8QM. |
| LDO Regulators | 4 × 400 mA LDOs (LDO1–LDO4, 1.5–5.0 V, ±3 %) with optional load switch mode - supplies low-noise analog, I/O, and auxiliary rails without external FETs. |
| RTC & Backup | VSNVS output (1.8/3.0/3.3 V, 10 mA) + LICELL input (up to 4.2 V) with programmable coin cell charge current/voltage - maintains real-time clock and SRAM during main power loss. |
| I²C Interface | High-speed up to 3.4 MHz - enables rapid runtime reconfiguration of voltages, sequencing, and protection thresholds without interrupting system operation. |
| Package | HVQFN56, 8 mm × 8 mm × 0.85 mm, 0.5 mm pitch, non-wettable flank (EP suffix) - thermally enhanced for industrial ambient (−40 °C to +105 °C). |
| Safety Certification | QM (Quality Management) grade - includes ASIL B–compliant monitoring (voltage, thermal, watchdog), but excludes PF8200's fail-safe output (FSOB) and ABIST-on-demand features. |
Pinout & Package
HVQFN56 package (SOT684-21), 8 mm × 8 mm × 0.85 mm body, exposed thermal pad (EPAD) soldered to PCB ground plane for optimal thermal dissipation in industrial applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW1FB–SW7FB | Buck feedback inputs | Enable precise closed-loop regulation; support resistor-divider programming of output voltage (e.g., SW1FB sets SW1 output between 0.4–1.8 V). |
| SW1IN–SW7IN | Buck input supplies | Accept 2.7–5.5 V input; SW1IN–SW4IN share VIN domain, SW5IN–SW7IN may be independently routed for noise isolation. |
| SW1LX–SW7LX | Switching node outputs | Connect to external inductors; transient-tolerant to −3.0 V spikes during dead time - requires tight layout to minimize parasitic inductance. |
| LDO1OUT–LDO4OUT | LDO regulated outputs | Deliver low-noise, fixed/programmable voltages (1.5–5.0 V); LDO2EN allows hardware-controlled enable/disable of LDO2. |
| VSNVS, LICELL | RTC supply & backup input | VSNVS provides 1.8/3.0/3.3 V to SNVS domain; LICELL accepts coin cell (≤4.2 V) for battery-backed retention during main power loss. |
| SCL, SDA | I²C communication interface | Support 3.4 MHz high-speed mode; require pull-up resistors to VDDIO (1.6–3.3 V); enable runtime tuning of regulators and safety parameters. |
| RESETBMCU, INTB, EWARN | System control signals | Open-drain outputs: RESETBMCU asserts active-low reset to i.MX8QM; INTB signals faults/events; EWARN warns of impending thermal/voltage violation. |
| EPAD | Thermal pad | Must be connected to solid ground plane - critical for achieving RθJB = 11 °C/W and maintaining TJ ≤ 150 °C at full load. |
Key Features
| Feature | Design Value |
|---|---|
| OTP-configurable startup | Stores voltage setpoints, power-up sequence, and protection thresholds in one-time programmable memory - eliminates 12+ external resistors and simplifies BOM. |
| Multi-phase buck capability | SW1/SW2, SW3/SW4, or SW5/SW6 can be paired as dual-phase regulators (5 A total); SW1/SW2/SW3 support triple-phase (7.5 A) for CPU core rails. |
| VTT termination on SW6 | Configurable as DDR VTT supply (0.4–1.8 V, 2.5 A) with precision tracking - directly supports LPDDR4 memory termination without external components. |
| 24-channel analog multiplexer | Routes internal voltage/temperature monitors to AMUX pin for external ADC sampling - enables real-time system health diagnostics without added sensors. |
| Programmable watchdog & fault response | WDI input accepts MCU watchdog pulses; configurable timeout and fail-safe behavior (e.g., RESETBMCU assertion, regulator shutdown) on fault detection. |
