Product details
Overview
MC34PF8100CFEP from NXP Semiconductors is an industrial-grade 12-channel power management IC (PMIC) designed for i.MX 8QXP processors with DDR3L memory. It integrates seven high-efficiency buck converters (0.4–1.8 V, 2.5 A each), four 400 mA LDOs, RTC supply (VSNVS), coin cell charger, watchdog timer, and ASIL-B-compliant monitoring circuitry. It supports dynamic voltage scaling, programmable power-up/down sequencing, and operates from 2.7–5.5 V input.
For engineers reviewing the MC34PF8100CFEP datasheet, MC34PF8100CFEP pinout, MC34PF8100CFEP application, or MC34PF8100CFEP equivalent, this page delivers verified specifications, validated pin functions, confirmed industrial use cases for i.MX 8QXP-based systems, and two technically documented alternative PMICs with explicit functional and safety-grade differences.
Technical Context
The MC34PF8100CFEP implements a deterministic state machine for fault-aware startup, runtime monitoring, and fail-safe transitions-including thermal shutdown, UV/OV detection, watchdog timeout handling, and PGOOD assertion. Its 24-channel analog multiplexer enables real-time system diagnostics across all regulator outputs and critical nodes.
It features OTP-programmable configuration for voltage setpoints, sequencing order, soft-start timing, and safety thresholds-reducing external component count while enabling post-power-on I²C reconfiguration at up to 3.4 MHz. The device supports dual-, triple-, and quad-phase configurations for SW1–SW4 to deliver up to 10 A peak current with tight regulation accuracy (±1.5 % for bucks, ±3 % for LDOs).

Equivalent & Alternatives
The following parts are listed as comparable options for similar power management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC34PF8200DFEP | ASIL-B safety certification (vs. QM for MC34PF8100CFEP); adds FSOB fail-safe output, ABIST-on-demand, secure I²C write, and enhanced fault counters | Required for automotive infotainment or industrial safety-critical subsystems needing ISO 26262 compliance | Select when functional safety certification is mandatory; not drop-in due to OTP and register map differences |
| MC33PF8100CFES | Automotive-qualified (AEC-Q100 Grade 2); identical regulator topology and pinout but rated for −40°C to +125°C junction and higher ESD robustness (2 kV HBM) | Targeted for automotive infotainment head units using i.MX 8QXP with DDR3L memory | Choose for automotive production; shares same OTP configuration files but requires qualification testing per vehicle program |
Compared with MC34PF8100CFEP, MC34PF8200DFEP adds certified safety features at the cost of increased design validation effort, while MC33PF8100CFES offers automotive environmental ruggedness without safety extensions-making MC34PF8100CFEP optimal for cost-sensitive, non-safety industrial designs requiring i.MX 8QXP support.

FAQ
What is the input voltage range supported by the MC34PF8100CFEP?
The MC34PF8100CFEP supports a main input voltage range of 2.7 V to 5.5 V on its VIN pin (Pin 50). This range accommodates standard industrial 3.3 V and 5 V supply rails, and the device includes UVLO detection at approximately 2.7 V to prevent erratic operation during brownout conditions. Absolute maximum rating is 6.0 V, but continuous operation above 5.5 V is limited to 1800 seconds over lifetime.
Does the MC34PF8100CFEP support DDR3L memory termination?
Yes, the MC34PF8100CFEP supports DDR3L memory termination via SW6, which can be configured in VTT mode. SW6 delivers programmable sink/source current with tracking compliance to DDR3L standards, and its output voltage is adjustable between 0.4 V and 1.8 V. This capability is explicitly confirmed in the functional block diagram and power tree summary for MC34PF8100CFEP.
What safety level does the MC34PF8100CFEP meet?
The MC34PF8100CFEP is qualified to QM (Quality Management) level-not ASIL-B. While it includes monitoring circuits compatible with ASIL-B requirements (voltage, thermal, watchdog), it lacks the certified fault-handling mechanisms (e.g., FSOB, ABIST-on-demand, secure I²C) found in the PF8200 series. Its safety documentation confirms QM classification per Table 2 ordering information.
Can the MC34PF8100CFEP be used with i.MX 8QM processors?
No-MC34PF8100CFEP is specifically configured for i.MX 8QXP with DDR3L memory, as stated in Table 2 of the datasheet. For i.MX 8QM, NXP lists MC34PF8100CHEP (DDR4 PMIC2) and MC34PF8100EPEP (LPDDR4 PMIC1) as the designated industrial variants. Using MC34PF8100CFEP with i.MX 8QM would mismatch OTP configuration, power tree, and sequencing requirements.
What package type and thermal characteristics apply to the MC34PF8100CFEP?
The MC34PF8100CFEP uses the HVQFN56 package (SOT684-21), 8 mm × 8 mm × 0.85 mm, with non-wettable flanks (EP suffix). Its thermal resistance is RθJA = 27 °C/W on a 4-layer board, RθJB = 11 °C/W to PCB, and RθJC = 0.6 °C/W to case bottom-enabling reliable operation up to 105 °C ambient with proper copper pour and EPAD soldering.
