Product details
Overview
MC33PF8100ERESR2 from NXP Semiconductors is an automotive-grade 12-channel power management IC (PMIC) designed for i.MX8QM processors with DDR4 memory (PMIC1 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. It operates from 2.7 V to 5.5 V input and supports dynamic voltage scaling for CPU/GPU/memory rails in infotainment systems.
For engineers reviewing the MC33PF8100ERESR2 datasheet, MC33PF8100ERESR2 pinout, MC33PF8100ERESR2 application, or MC33PF8100ERESR2 equivalent, key selection criteria include its OTP-configurable startup sequence, 3.4 MHz I²C interface, 56-pin HVQFN package with wettable flanks, and support for dual/triple/quad-phase configurations on buck channels SW1–SW4.
Technical Context
The MC33PF8100ERESR2 implements a deterministic state machine for fault-aware power sequencing, with programmable soft-start/power-down sequences and fail-safe transitions triggered by thermal, voltage, or watchdog failures. Its internal 24-channel analog multiplexer enables real-time system diagnostics across all regulated outputs and critical nodes.
It features hardware-based safety monitoring including independent voltage monitors per regulator, ABIST (analog built-in self-test), and programmable fault counters - all meeting ASIL B requirements per ISO 26262. The device uses OTP memory to store boot configuration, eliminating external resistors for voltage setpoints and sequencing order.

FAQ
What is the primary application target for MC33PF8100ERESR2?
The MC33PF8100ERESR2 is specifically configured for i.MX8QM processors with DDR4 memory in the PMIC1 role. It powers CPU cores, GPU, DDR4 memory (including VTT termination), and peripherals in automotive infotainment and ADAS systems. Its OTP configuration matches the MC33PF8100ER.zip reference design, ensuring compatibility with NXP's validated power tree for this platform.
Does MC33PF8100ERESR2 support dynamic voltage scaling (DVS)?
Yes, MC33PF8100ERESR2 supports DVS on buck regulators SW1 through SW6. Each can be individually programmed via I²C to adjust output voltage in 6.25 mV steps within their respective ranges (e.g., SW1: 0.4–1.8 V). This enables real-time optimization of CPU/GPU voltage based on performance demands, reducing dynamic power consumption in active states.
What safety features does MC33PF8100ERESR2 provide for automotive use?
MC33PF8100ERESR2 meets ASIL B requirements with independent voltage monitors per regulator, thermal shutdown at 150 °C, watchdog timer with programmable timeout, ABIST (analog built-in self-test), and fail-safe output (FSOB). It lacks PF8200's full ABIST coverage and secure I²C write, but retains core monitoring functions required for QM-level automotive systems.
How is the RTC supply implemented in MC33PF8100ERESR2?
MC33PF8100ERESR2 provides RTC power via the VSNVS output, configurable for 1.8 V, 3.0 V, or 3.3 V operation. It draws from either main VIN or a backup coin cell connected to LICELL pin. The integrated coin cell charger supports programmable charge current and voltage, ensuring reliable timekeeping during vehicle ignition-off periods.
What package variant does MC33PF8100ERESR2 use, and why does it matter?
MC33PF8100ERESR2 uses the HVQFN56 package with dimple wettable flanks (SOT684-29(D)). This enables automated optical inspection (AOI) of solder joints in automotive manufacturing - a critical requirement for zero-defect assembly. The 0.9 mm height and exposed thermal pad also improve heat dissipation in space-constrained infotainment modules.
