NXP Semiconductors MMPF0100F3ANESR2

Overview

MMPF0100F3ANESR2 from NXP Semiconductors is a 14-channel configurable power management IC (PMIC) designed for i.MX 6-based embedded platforms. It integrates six buck converters (including SW1A/B/C, SW2, SW3A/B, SW4), six LDOs (VGEN1–VGEN6), RTC supply, coin-cell charger, DDR termination reference (VREFDDR), and I²C programmable control logic. It operates from a 2.8–4.5 V main input and supports -40 °C to +105 °C industrial ambient temperature range.

For engineers reviewing the MMPF0100F3ANESR2 datasheet, MMPF0100F3ANESR2 pinout, MMPF0100F3ANESR2 application, or MMPF0100F3ANESR2 equivalent, key selection criteria include OTP-programmable power sequencing, DDR memory interface support (VREFDDR tracking), thermal protection thresholds (110–130 °C interrupts), and compatibility with i.MX 6SoloLite reference designs per NXP documentation.

Technical Context

The MMPF0100F3ANESR2 implements a hierarchical power tree with independent state machine control for startup, standby, and shutdown sequences. Its architecture includes dual-phase capable buck regulators (SW1A/B, SW3A/B), a dedicated DDR termination reference generator (VREFDDR), and an integrated Li-ion coin-cell charger (LICELL) with VSNVS LDO/switch output for always-on domain power.

Control is executed via I²C interface (SCL/SDA, 3.6 V tolerant) with register-mapped configuration of voltage levels, timing delays, and enable/disable states. OTP memory stores boot-time configuration, and thermal monitoring uses four interrupt-enabled thresholds (THERM110I–THERM130I) with 8 ms debounce to prevent false trips.

FAQ

What is the primary function of the MMPF0100F3ANESR2 in an i.MX 6-based design?

The MMPF0100F3ANESR2 serves as the central power management IC for i.MX 6SoloLite platforms, delivering and sequencing all required voltage rails-including VCOREDIG (1.5 V), VCORE (1.5 V), VGEN2 (2.5 V), VGEN4 (3.5 V), and VREFDDR (0.75 V)-while integrating coin-cell charging and thermal protection. Its OTP configuration is pre-validated for SoloLite reference designs, eliminating manual sequencing setup.

Does the MMPF0100F3ANESR2 support DDR memory termination, and how is it implemented?

Yes, the MMPF0100F3ANESR2 includes a dedicated DDR termination reference generator. It uses three pins-VHALF (half-supply reference), VINREFDDR (input), and VREFDDR (output)-to produce a precise, trackable termination voltage (typically 0.75 V) that follows VDDQ/2. This implementation meets JEDEC DDR3/DDR4 specifications without external resistors or op-amps.

What thermal protection features does the MMPF0100F3ANESR2 provide, and how are they signaled?

The MMPF0100F3ANESR2 provides four programmable thermal interrupt thresholds (110 °C, 120 °C, 125 °C, 130 °C), each generating a dedicated flag (THERM110I–THERM130I) accessible via I²C register INTSENSE0. An open-drain INTB pin asserts on any threshold breach, and automatic shutdown occurs above 130 °C with 8 ms debounce to prevent noise-induced trips.

Can the MMPF0100F3ANESR2 be used with coin-cell backup, and what rails does it support?

Yes, the MMPF0100F3ANESR2 supports coin-cell backup via the LICELL pin (1.8–3.6 V input) and delivers regulated power through the VSNVS LDO output (3.0 V ±3%). This rail powers always-on domains such as RTC, backup SRAM, and wake-up logic-enabling zero-power retention during main supply loss without external charging circuitry.

How does the OTP programming of the MMPF0100F3ANESR2 differ from non-programmed variants like MMPF0100NPANESR2?

The MMPF0100F3ANESR2 contains factory-programmed OTP fuses defining voltage levels, sequencing order, timing delays, and DVS settings specific to i.MX 6SoloLite. In contrast, MMPF0100NPANESR2 ships unprogrammed-requiring customer OTP programming or runtime I²C configuration. F3 OTP eliminates boot-time register writes and ensures deterministic power-up behavior out-of-box.
