Product details
Overview
MC34PF8100EQEP from NXP Semiconductors is an industrial-grade 12-channel power management IC (PMIC) designed for i.MX 8QM processors with LPDDR4 memory (PMIC2 role). It integrates seven high-efficiency buck converters (SW1–SW7), four linear regulators (LDO1–LDO4), RTC supply (VSNVS), coin cell charger, watchdog timer, and ASIL-B-compliant monitoring circuitry. Input voltage range is 2.7 V to 5.5 V, and it supports dynamic voltage scaling across six buck channels.
For engineers reviewing the MC34PF8100EQEP datasheet, MC34PF8100EQEP pinout, MC34PF8100EQEP application, or MC34PF8100EQEP equivalent, this page delivers verified specifications, validated pin functions, confirmed industrial use cases for i.MX 8QM-based systems, and two technically documented alternative PMICs with explicit functional and safety-grade differences.
Technical Context
The MC34PF8100EQEP implements a deterministic state machine for startup sequencing, fault detection, and fail-safe transitions - including PGOOD monitoring, thermal shutdown at 150 °C, and programmable soft-start/power-down sequences. Its architecture supports multi-phase configurations: SW1/SW2 as dual-phase, SW3/SW4 as dual-phase, SW5/SW6 as dual-phase, and SW1/SW2/SW3 as triple-phase (up to 7.5 A).
It features a 24-channel analog multiplexer for system diagnostics, OTP memory storing boot configuration (voltage levels, sequencing order), and high-speed I²C interface operating up to 3.4 MHz. The device includes independent voltage monitors with programmable fault thresholds, ABIST for analog self-test, and external synchronization via SYNCIN/SYNCOUT pins.

FAQ
What is the input voltage range supported by the MC34PF8100EQEP?
The MC34PF8100EQEP supports a main input voltage range of 2.7 V to 5.5 V on the VIN pin. Regulator input supplies (SWxIN, LDOxIN, LICELL) are rated for −0.3 V to 6.0 V absolute maximum, but sustained operation above 5.5 V is limited to ≤1800 seconds over device lifetime per datasheet Table 4. The recommended operating range remains 2.7–5.5 V for reliability and thermal performance.
Does the MC34PF8100EQEP support dynamic voltage scaling (DVS)?
Yes, the MC34PF8100EQEP supports DVS on SW1 through SW6 buck regulators. Each can be programmed via I²C to adjust output voltage in 6.25 mV steps across their respective ranges (0.4–1.8 V). This enables real-time adaptation to CPU/GPU load states, reducing power consumption during low-activity periods while maintaining stability during burst workloads.
What safety features does the MC34PF8100EQEP include?
The MC34PF8100EQEP includes ASIL B-compliant monitoring circuitry: independent voltage monitors with programmable fault thresholds, thermal shutdown at 150 °C, watchdog timer with early warning (EWARN) and reset (RESETBMCU), and analog built-in self-test (ABIST). It does not implement full ASIL B fault containment - that capability is reserved for the PF8200 family.
Can the MC34PF8100EQEP be used with i.MX 8QXP processors?
No - the MC34PF8100EQEP is specifically configured for i.MX 8QM with LPDDR4 memory (PMIC2 role), as indicated in Table 2 of the datasheet. For i.MX 8QXP, NXP specifies variants like MC34PF8100CCEP (LPDDR4) or MC34PF8100CFEP (DDR3L). Using MC34PF8100EQEP with i.MX 8QXP may result in incorrect power sequencing or unsupported voltage rail configurations.
What is the purpose of the VSNVS pin on the MC34PF8100EQEP?
The VSNVS pin on the MC34PF8100EQEP delivers a regulated 1.8 V, 3.0 V, or 3.3 V output (selectable via OTP) at up to 10 mA for the SNVS (Secure Non-Volatile Storage) domain and real-time clock (RTC). It can be powered from either the main VIN supply or an external coin cell connected to LICELL - ensuring continuous RTC operation and secure key storage during main power loss.
