Product details
Overview
MC34PF8100CFEPR2 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 with load switch options, RTC supply (VSNVS), coin cell charger, watchdog timer, and ASIL B–capable monitoring circuitry. It powers CPU cores, GPU, DDR I/O, and peripherals in automotive infotainment and industrial HMI systems.
For engineers reviewing the MC34PF8100CFEPR2 datasheet, MC34PF8100CFEPR2 pinout, MC34PF8100CFEPR2 application, or MC34PF8100CFEPR2 equivalent, this page delivers verified technical context, exact regulator specifications, validated HVQFN56 pin mapping, real-world use cases for i.MX 8QXP-based designs, and two confirmed alternative PMICs with documented functional differences.
Technical Context
The MC34PF8100CFEPR2 implements a deterministic state machine for fault-aware startup, power sequencing, and fail-safe transitions-including hard watchdog reset, critical thermal shutdown (TJ > 150 °C), and VIN UVLO recovery. Its OTP memory stores boot-time voltage setpoints and sequencing order, eliminating external configuration resistors.
It supports dynamic voltage scaling on six buck channels (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. The 3.4 MHz I²C interface enables runtime reconfiguration of regulators, soft-start timing, and monitoring thresholds.

FAQ
What is the input voltage range supported by MC34PF8100CFEPR2?
The MC34PF8100CFEPR2 accepts a main input voltage (VIN) from 2.7 V to 5.5 V. Buck regulator inputs (SWxIN) and LDO inputs (LDOxIN) also operate within −0.3 V to 6.0 V absolute maximum, with recommended operating range matching VIN. This range supports common industrial supplies including 3.3 V, 5 V, and battery-backed 4.2 V sources.
Does MC34PF8100CFEPR2 support dynamic voltage scaling (DVS)?
Yes, MC34PF8100CFEPR2 supports DVS on SW1 through SW6 buck converters. Each can be programmed via I²C to adjust output voltage in 6.25 mV steps across 0.4–1.8 V, enabling real-time adaptation to processor performance states (e.g., Cortex-A72 frequency scaling). SW7 does not support DVS due to its wider 1.0–4.1 V range.
How is the RTC supply (VSNVS) configured on MC34PF8100CFEPR2?
The VSNVS rail on MC34PF8100CFEPR2 is configurable for 1.8 V, 3.0 V, or 3.3 V output and draws power either from VIN or a coin cell connected to LICELL. It delivers up to 10 mA and includes a programmable coin cell charger with adjustable charge current and voltage-ensuring reliable RTC operation during main power loss without external circuitry.
What safety features does MC34PF8100CFEPR2 include for industrial applications?
MC34PF8100CFEPR2 incorporates ASIL B–capable monitoring: independent voltage monitors for all 12 outputs, thermal shutdown at 150 °C junction temperature, watchdog timer with programmable timeout, I²C CRC protection, and analog built-in self-test (ABIST). While not certified for ASIL B, its architecture meets key diagnostic coverage requirements for industrial functional safety.
Can MC34PF8100CFEPR2 be used with processors other than i.MX 8QXP?
Yes, MC34PF8100CFEPR2 is compatible with other NXP processors including i.MX 8QM and LS1046A, as well as select non-NXP SoCs. Its flexible OTP configuration, 12-channel architecture, and wide output ranges make it adaptable-but reference designs, startup sequences, and I²C initialization scripts must be validated per target platform.
