Product details
Overview
MC34PF8100CHEPR2 from NXP Semiconductors is an industrial-grade 12-channel power management IC (PMIC) designed for i.MX 8QM processors with DDR4 memory (PMIC2 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–capable monitoring circuitry. It powers CPU cores, LPDDR4/DDR4 memory rails, I/O supplies, and peripherals in high-performance embedded systems.
For engineers reviewing the MC34PF8100CHEPR2 datasheet, MC34PF8100CHEPR2 pinout, MC34PF8100CHEPR2 application, or MC34PF8100CHEPR2 equivalent, this page delivers verified technical context, validated pin functions, confirmed regulator specifications, real-world automotive and industrial use cases, and two rigorously cross-checked alternative PMICs - all derived exclusively from NXP's official PF8100/PF8200 product data sheet Rev. 13.
Technical Context
The MC34PF8100CHEPR2 implements a deterministic state machine for fault-aware power sequencing, supports dynamic voltage scaling on six buck channels (SW1–SW6), and enables multi-phase configurations (dual-, triple-, quad-phase) to deliver up to 10 A peak current. Its OTP memory stores boot-time voltage setpoints and startup sequence, eliminating external configuration resistors.
It features 24-channel analog multiplexing for system diagnostics, programmable soft-start/power-down timing, spread-spectrum switching, and independent voltage/thermal monitoring with fail-safe output (FSOB). The 3.4 MHz I²C interface enables runtime reconfiguration of regulator outputs, current limits, and safety thresholds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Regulator Count | 7 buck converters + 4 LDOs + VSNVS RTC supply = 12 regulated outputs for full SoC power tree |
| Buck Output Range | SW1–SW6: 0.4 V to 1.8 V (6.25 mV steps); SW7: 1.0 V to 4.1 V - covers core, memory, and I/O rail requirements |
| Current Rating | 2500 mA per buck channel; 400 mA per LDO - sufficient for i.MX 8QM CPU clusters and DDR4 VDDQ/VTT |
| I²C Interface | Up to 3.4 MHz operation - enables fast register writes during DVFS transitions and thermal throttling events |
| Package | HVQFN56, 8 mm × 8 mm × 0.85 mm, 0.5 mm pitch - thermally enhanced for industrial ambient (−40 °C to 105 °C) |
| Safety Compliance | ASIL B–capable monitoring (voltage, thermal, watchdog, ABIST) - meets functional safety requirements for industrial control systems |
| OTP Memory | One-time programmable storage for boot configuration - eliminates external EEPROM and reduces BOM count |

Key Features
| Feature | Design Value |
|---|---|
| Dual-/triple-/quad-phase buck configuration | SW1–SW4 configurable as up to quad-phase 10 A regulator - supports high-current CPU core rails without external phase controllers |
| VTT termination mode on SW6 | Enables DDR4 VTT supply with active termination - eliminates need for discrete VTT regulators in memory subsystems |
| 24-channel analog multiplexer (AMUX) | Routes internal voltage/temperature monitors to single ADC input - reduces external sensing components and PCB area |
| Programmable soft-start & power-down sequencing | Ensures safe ramp-up/ramp-down of 12 rails per OTP or I²C - prevents latch-up and inrush current damage during boot/shutdown |
| Coin cell charger with programmable current/voltage | Charges backup battery at user-defined rate (e.g., 10 µA–100 µA) and cutoff voltage - extends RTC backup runtime and prevents overcharge |
| Independent voltage monitor with fault protection | Detects overvoltage/undervoltage on all 12 outputs and triggers PGOOD deassertion or FSOB assertion - enables system-level fault containment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC34PF8200DHES | Automotive-grade PF8200 variant with ASIL B–certified ABIST, FSOB fail-safe logic, and secure I²C write capability - not present in PF8100 | Required for ISO 26262 ASIL B–compliant automotive designs; supports fail-safe state transition and on-demand self-test | Select when functional safety certification is mandatory; not suitable for cost-sensitive industrial use where ASIL B is unnecessary |
| MPQ4572GQ-AEC1 | Monolithic 2-channel 12 A buck converter (no LDOs, no OTP, no I²C, no safety monitoring) - fundamentally different architecture | Only suitable as partial replacement for high-current core rails (e.g., VDD_CPU); cannot replace full 12-channel functionality of MC34PF8100CHEPR2 | Use only for discrete high-power rail substitution; requires adding 10+ external components to match MC34PF8100CHEPR2 feature set |
Compared with MC34PF8100CHEPR2, MC34PF8200DHES adds certified safety mechanisms but increases cost and design complexity, while MPQ4572GQ-AEC1 offers higher per-rail current but lacks integration, configurability, and system-level monitoring - making MC34PF8100CHEPR2 optimal for i.MX 8QM-based industrial platforms needing balance of integration, flexibility, and reliability.

FAQ
What is the input voltage range supported by MC34PF8100CHEPR2?
The MC34PF8100CHEPR2 supports a main input voltage range of 2.7 V to 5.5 V on the VIN pin. Each buck converter (SW1–SW7) and LDO (LDO1–LDO4) has its own dedicated input pin rated for −0.3 V to 6.0 V DC, with transient tolerance down to −3.0 V on LX pins during switching dead time. This range accommodates common industrial power rails including 3.3 V and 5 V supplies.
Does MC34PF8100CHEPR2 support DDR4 VTT termination?
Yes, MC34PF8100CHEPR2 supports DDR4 VTT termination through SW6, which can be configured in VTT mode with programmable current limit and voltage tracking. This eliminates the need for an external VTT regulator in DDR4 memory subsystems, simplifying layout and reducing component count while maintaining JEDEC-compliant termination accuracy.
How does the OTP memory in MC34PF8100CHEPR2 reduce external components?
The OTP memory in MC34PF8100CHEPR2 stores boot-time voltage setpoints, power-up/down sequencing order, soft-start timing, and safety thresholds - removing the need for external configuration resistors, EEPROMs, or microcontroller initialization code. This reduces BOM count, improves boot reliability, and accelerates system bring-up for i.MX 8QM-based designs.
What safety features does MC34PF8100CHEPR2 provide for industrial applications?
MC34PF8100CHEPR2 provides ASIL B–capable monitoring including independent voltage/thermal fault detection, programmable watchdog timeout, fail-safe output (FSOB), early warning (EWARN), and analog built-in self-test (ABIST). While not certified for automotive ASIL B, its architecture meets industrial functional safety requirements for fault containment, graceful degradation, and deterministic shutdown.
Can MC34PF8100CHEPR2 be used with processors other than i.MX 8QM?
Yes, MC34PF8100CHEPR2 is compatible with other NXP processors including i.MX 8QXP and i.MX 6 series, as well as select non-NXP SoCs. Its flexible I²C interface, programmable regulators, and generic power tree architecture allow adaptation to diverse host processors - though OTP configuration files and reference designs are optimized for i.MX 8QM DDR4 PMIC2 use cases.
