Product details
Overview
MC34PF8100EREPR2 from NXP Semiconductors is an industrial-grade 12-channel power management IC (PMIC) designed for i.MX 8QXP and i.MX 8QM application processors. It integrates seven high-efficiency buck converters (0.4–1.8 V, 2.5 A each), four 400 mA LDOs with load-switch capability, RTC supply (VSNVS), coin-cell charging, watchdog timer, and ASIL B-compliant monitoring circuitry. It powers CPU cores, LPDDR4/DDR4 memory, and I/O peripherals in high-performance embedded systems.
For engineers reviewing the MC34PF8100EREPR2 datasheet, MC34PF8100EREPR2 pinout, MC34PF8100EREPR2 application, or MC34PF8100EREPR2 equivalent, this page delivers verified technical context, exact regulator specifications, validated HVQFN56 pin mapping, real-world use cases for automotive infotainment and industrial edge computing, and two confirmed alternative PMICs with documented functional differences.
Technical Context
The MC34PF8100EREPR2 implements a deterministic state machine for fault-aware startup, sequencing, and fail-safe transitions - including hard watchdog reset, critical thermal shutdown (TJ > 150 °C), and VIN undervoltage lockout. Its OTP memory stores boot-time voltage setpoints and power-up sequence order, eliminating external configuration resistors.
It supports dynamic voltage scaling on six buck channels (SW1–SW6), triple-phase operation (up to 7.5 A on SW1–SW3), quad-phase mode (up to 10 A on SW1–SW4), and VTT termination on SW6. All regulators are programmable via 3.4 MHz I²C with CRC-protected register writes and 24-channel analog multiplexer for system-level diagnostics.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC33PF8100CHTS | Automotive-grade variant with ASIL B certification; identical pinout and regulator architecture but includes additional safety features (ABIST on-demand, FSOB assertion logic). | Required for automotive production where ISO 26262 ASIL B compliance is mandatory; not qualified for industrial temperature range (−40 °C to 105 °C). | Select MC33PF8100CHTS only when functional safety certification is required; MC34PF8100EREPR2 remains optimal for industrial designs needing wider ambient tolerance and lower cost. |
| MC34PF8200EREP | Industrial PF8200 variant with enhanced safety features: AB_SWx_OV/UV monitors, fail-safe state machine (FS_CNT), and secure I²C write enable - absent in PF8100 family. | Supports higher-integrity diagnostics in medical or industrial control systems requiring runtime self-test and fail-safe lockdown. | Choose MC34PF8200EREP if ABIST-on-demand, programmable fail-safe timeout, or secure register locking are design requirements; otherwise, MC34PF8100EREPR2 offers full feature parity at lower complexity. |
Compared with MC33PF8100CHTS and MC34PF8200EREP, MC34PF8100EREPR2 delivers identical 12-channel regulation, OTP configuration, and I²C programmability while targeting cost-sensitive industrial applications without mandatory ASIL B certification - reducing qualification overhead and enabling faster time-to-market for non-automotive designs.

FAQ
What is the input voltage range supported by the MC34PF8100EREPR2?
The MC34PF8100EREPR2 accepts a main input voltage (VIN) from 2.7 V to 5.5 V. This range accommodates common intermediate rails such as 3.3 V and 5 V supplies, and supports operation directly from USB PD or industrial 5 V sources. The absolute maximum rating is 6.0 V, but sustained operation above 5.5 V is limited to 1800 seconds over the device lifetime to ensure reliability.
Does the MC34PF8100EREPR2 support dynamic voltage scaling (DVS)?
Yes, the MC34PF8100EREPR2 supports DVS on six buck regulators (SW1–SW6). Each can be programmed in 6.25 mV steps across 0.4 V to 1.8 V, enabling real-time voltage adjustment during CPU frequency scaling. DVS is controlled via the 3.4 MHz I²C interface and coordinated through the internal state machine to maintain sequencing integrity.
How does the MC34PF8100EREPR2 handle thermal protection?
The MC34PF8100EREPR2 integrates die-temperature monitoring with programmable thermal shutdown at 150 °C junction temperature. It also provides 10× on-die temperature sensors and supports thermal derating via I²C - allowing system firmware to reduce output current or disable non-critical rails before reaching critical thresholds. The EPAD thermal pad ensures RθJC = 0.6 °C/W for efficient heat transfer.
Can the MC34PF8100EREPR2 power LPDDR4 memory directly?
Yes, the MC34PF8100EREPR2 is explicitly validated for LPDDR4 memory powering in i.MX 8QXP and i.MX 8QM platforms. SW3 and SW4 provide 1.1 V and 1.2 V VDDQ rails with ±1.5% accuracy, while SW6 operates in VTT termination mode for precise 0.6 V tracking - meeting JEDEC LPDDR4 specifications without external components.
What safety features does the MC34PF8100EREPR2 include?
The MC34PF8100EREPR2 includes ASIL B-compliant monitoring: independent voltage monitors for all 12 outputs, advanced thermal protection, external watchdog input (WDI), early warning output (EWARN), fail-safe output (FSOB), and analog built-in self-test (ABIST). While it lacks PF8200's ABIST-on-demand and secure I²C, its monitoring circuitry satisfies QM (Quality Management) level requirements for industrial and non-safety-critical automotive functions.
