Product details
Overview
MC34PF8100F3EPR2 from NXP Semiconductors is an industrial-grade 12-channel power management IC (PMIC) designed for LA1575-based systems with LPDDR4 memory. 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 processor core and memory rail optimization.
For engineers reviewing the MC34PF8100F3EPR2 datasheet, MC34PF8100F3EPR2 pinout, MC34PF8100F3EPR2 application, or MC34PF8100F3EPR2 equivalent, this page delivers verified specifications, validated pin functions, confirmed industrial use cases for LPDDR4-powered edge devices, and two technically documented alternative PMICs compatible with i.MX 8 and LA1575 platforms.
Technical Context
The MC34PF8100F3EPR2 implements a deterministic state machine for fault-aware power sequencing, with OTP-programmed startup configuration and runtime I²C reconfiguration at up to 3.4 MHz. Its seven buck regulators include SW1–SW6 (0.4 V–1.8 V, ±1.5 % accuracy, 2.5 A each) and SW7 (1.0 V–4.1 V, ±2 %, 2.5 A), supporting multi-phase configurations (dual/triple/quad) and VTT termination on SW6.
Four P-type LDOs (LDO1–LDO4) deliver 1.5 V–5.0 V at 400 mA with ±3 % accuracy and optional load-switch mode. Integrated safety features include independent voltage/thermal monitoring, ABIST, programmable watchdog timeout, and fail-safe output (FSOB), all meeting ASIL B functional safety requirements per ISO 26262.

Equivalent & Alternatives
The following parts are listed as comparable options for similar power management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC34PF8200FJTS | Includes full ASIL B safety features (ABIST, FSOB, secure I²C, fail-safe state) not present in MC34PF8100F3EPR2 | Required for automotive ASIL B-certified systems; not needed for industrial LA1575 applications | Select MC34PF8200FJTS only if functional safety certification is mandated; otherwise MC34PF8100F3EPR2 offers lower cost and identical power capability |
| MPQ4436-AEC1 | Single 3A buck converter (no integrated LDOs, no OTP, no I²C, no safety monitoring) | Requires external LDOs, sequencer, and safety logic - increases design complexity and footprint | Use MPQ4436-AEC1 only for simple point-of-load replacement; MC34PF8100F3EPR2 provides full-system integration for LA1575 platforms |
Compared with MC34PF8200FJTS, MC34PF8100F3EPR2 omits redundant safety logic for industrial use, reducing cost and enabling faster qualification. Versus MPQ4436-AEC1, it delivers complete 12-rail power architecture with sequencing, monitoring, and memory interface support - eliminating 11 discrete regulators and associated passive components.

FAQ
What is the input voltage range supported by the MC34PF8100F3EPR2?
The MC34PF8100F3EPR2 supports a main input voltage range of 2.7 V to 5.5 V on its VIN pin. This allows direct connection to common industrial power rails such as 3.3 V or 5 V supplies. The device also accepts coin cell input (LICELL) up to 4.2 V for RTC backup, and regulator-specific inputs (e.g., SW1IN, LDO12IN) share the same absolute maximum rating of −0.3 V to 6.0 V.
Does the MC34PF8100F3EPR2 support dynamic voltage scaling (DVS)?
Yes, the MC34PF8100F3EPR2 supports dynamic voltage scaling on SW1 through SW6 - all six primary buck regulators. DVS is implemented via I²C commands that adjust output voltage in 6.25 mV steps within their respective ranges (0.4 V–1.8 V). This enables real-time power/performance tuning for LA1575 and i.MX 8 processors during varying computational loads.
How does the MC34PF8100F3EPR2 handle functional safety requirements?
The MC34PF8100F3EPR2 includes a monitoring circuit certified to ASIL B per ISO 26262, featuring independent voltage/thermal fault detection, programmable watchdog timeout, ABIST, and fail-safe output (FSOB). While it lacks the full safety feature set of the PF8200 (e.g., secure I²C, fail-safe state), its ASIL B monitoring is sufficient for industrial systems where functional safety is required but full automotive certification is not mandated.
Can the MC34PF8100F3EPR2 power LPDDR4 memory directly?
Yes, the MC34PF8100F3EPR2 is explicitly configured for LPDDR4 memory support in LA1575 systems. SW5 and SW6 provide core and I/O supplies, while SW6 operates in VTT termination mode - eliminating the need for an external VTT regulator. The OTP configuration file MC34PF8100F3.zip confirms LPDDR4-specific startup sequences and voltage settings for this exact part number.
What package type and thermal characteristics does the MC34PF8100F3EPR2 use?
The MC34PF8100F3EPR2 uses the HVQFN56 (SOT684-21) package: 8 mm × 8 mm × 0.85 mm body, 0.5 mm pitch, with wettable flanks. Its thermal resistance is RθJA = 27 °C/W on a 4-layer board and RθJC = 0.6 °C/W to the case bottom. The exposed EPAD must be soldered to a solid GND plane to achieve rated thermal performance and sustain 10 A aggregate output current.
