Product details
Overview
MC34PF8100CHEP from NXP Semiconductors is a 12-channel industrial-grade power management IC (PMIC) designed for i.MX8QM-based DDR4 memory systems as PMIC2. 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, with 2.5 A per buck channel and 400 mA per LDO.
For engineers reviewing the MC34PF8100CHEP datasheet, MC34PF8100CHEP pinout, MC34PF8100CHEP application, or MC34PF8100CHEP equivalent, this page delivers verified technical context, exact pin functions, real-world use cases in automotive and industrial compute platforms, and validated alternative options - all grounded in NXP's PF8100/PF8200 Rev. 13 product data sheet.
Technical Context
The MC34PF8100CHEP implements a hierarchical power tree with seven synchronous buck regulators supporting dynamic voltage scaling (DVS) on SW1–SW6, configurable multi-phase operation (dual/triple/quad phase), and VTT termination on SW6. Its internal state machine manages startup sequencing, fault detection, and fail-safe transitions without MCU intervention.
It features OTP-programmable configuration storage, 24-channel analog multiplexer for system diagnostics, 3.4 MHz I²C interface, and integrated safety monitors including independent voltage/thermal supervision, ABIST, and programmable watchdog counters - all compliant with ASIL B functional safety requirements for industrial applications.

FAQ
What is the input voltage range supported by the MC34PF8100CHEP?
The MC34PF8100CHEP supports a main input voltage range of 2.7 V to 5.5 V on its VIN pin. This range accommodates standard 3.3 V and 5 V system rails, as well as battery-backed operation. Exceeding 5.5 V for more than 1800 seconds over the device lifetime may impact reliability, per NXP's absolute maximum ratings specification.
Does the MC34PF8100CHEP support DDR4 VTT termination?
Yes, the MC34PF8100CHEP supports DDR4 VTT termination through its SW6 buck regulator. SW6 can be configured in VTT mode with programmable current limit and voltage accuracy, eliminating the need for external termination ICs or resistor networks in i.MX8QM DDR4 memory subsystems.
How does the OTP memory in the MC34PF8100CHEP simplify system design?
The OTP memory in the MC34PF8100CHEP stores critical startup configurations - including output voltages, power-up/down sequencing order, and safety thresholds - eliminating external resistors, EEPROMs, or firmware initialization code. This reduces BOM count, improves boot reliability, and accelerates time-to-market for i.MX8QM-based platforms.
What safety features does the MC34PF8100CHEP include for industrial applications?
The MC34PF8100CHEP includes ASIL-B-compliant monitoring circuitry: independent over/under-voltage detection per rail, thermal shutdown, watchdog timer with programmable timeout, register CRC integrity checking, and analog built-in self-test (ABIST). These features meet functional safety requirements for industrial control and automation systems operating at QM safety grade.
Can the MC34PF8100CHEP be used with processors other than i.MX8QM?
Yes, the MC34PF8100CHEP is compatible with other NXP processors including i.MX8QXP and LS1046A, as well as select non-NXP high-performance SoCs. Its flexible 12-channel architecture, I²C configurability, and wide output voltage ranges allow adaptation to diverse power trees - though OTP configuration files are processor-specific and must be selected accordingly.
