Monolithic Power Systems Inc. MP2710GC-0000-Z

Overview

MP2710GC-0000-Z from Monolithic Power Systems is a 500mA, single-cell Li-ion/Li-polymer battery charger IC with integrated power-path management (PPM), I²C programmability, 1mA charge termination, <0.5μA battery leakage in shipping mode, and ±0.5% battery voltage regulation accuracy. It operates from 4.35V–5.5V input, supports simultaneous system powering and battery charging, and targets space-constrained portable devices such as TWS earbuds and smartwatches.

For engineers reviewing the MP2710GC-0000-Z datasheet, MP2710GC-0000-Z pinout, MP2710GC-0000-Z application, or MP2710GC-0000-Z equivalent, this device delivers configurable charge current (8–456mA), thermal regulation at 120°C, JEITA-compliant temperature profiling, and robust input over-voltage (6V) and under-voltage lockout (3.25V) protection - all in a 1.85mm × 1.85mm WLCSP-9 package.

Technical Context

The MP2710GC-0000-Z implements dual-MOSFET power-path architecture: a 290mΩ LDO FET between IN and SYS for regulated system supply, and a 100mΩ battery FET between BATT and SYS for seamless battery supplementation. Its I²C interface configures 8 critical parameters including I_{IN_LIMIT}, V_{SYS_REG} (4.2–4.95V), V_{BATT_REG} (3.6–4.53V), and pre-charge/fast-charge currents.

Charging logic executes three deterministic phases - pre-charge (configurable 1–31mA), constant-current fast-charge (8–456mA), and constant-voltage regulation - with 3.2s termination deglitch and auto-recharge triggered by 60–240mV drop below V_{BATT_REG}. Thermal regulation activates at 120°C, and shutdown occurs at 150°C with 20°C hysteresis.

FAQ

What is the maximum sustainable input voltage for MP2710GC-0000-Z?

The MP2710GC-0000-Z supports up to 21V continuous input voltage per absolute maximum ratings, but its functional operating range is 4.35V–5.5V. Input over-voltage protection triggers at 6.0V (±150mV hysteresis), clamping the LDO FET off to protect downstream circuitry - critical for USB-C PD or automotive accessory applications with transient spikes.

How does the power-path management handle simultaneous system load and battery charging?

MP2710GC-0000-Z prioritizes system load over battery charge. When input current is constrained (e.g., by I_{IN_LIMIT}), it dynamically reduces charge current to maintain regulated VSYS. If input power drops below system demand, the 100mΩ battery FET turns on to supplement load - ensuring uninterrupted operation even during partial input failure or cable disconnection.

Can the MP2710GC-0000-Z operate without an NTC thermistor?

Yes. The MP2710GC-0000-Z supports NTC-less JEITA operation: its internal bias current (50µA) and configurable cold/warm/hot thresholds allow temperature profiling using only the NTC pin voltage - eliminating the external 91kΩ pull-up resistor and reducing total solution current by ~2µA in active mode.

What is the purpose of the INT pin beyond fault signaling?

The INT pin serves dual roles: (1) open-drain interrupt output for charge status (e.g., EOC, FAULT) and (2) hardware-controlled battery isolation. Pulling INT low forces the battery FET off, disconnecting BATT from SYS - enabling system-level reset or safe battery removal without software intervention.

How is shipping mode exited, and what triggers automatic exit?

Shipping mode exits automatically upon VIN plug-in (detected after 80ms deglitch) or by pulling the INT pin low for ≥2 seconds. No I²C communication is required post-exit - the device resumes normal operation with default register values, enabling zero-touch activation in end-user devices.

Does MP2710GC-0000-Z support battery under-voltage lockout (UVLO) with hysteresis?

Yes. Battery UVLO is configurable via REG01h[2:0] with three thresholds: 2.4V (default), 2.76V, or 3.03V. Each setting includes 190mV hysteresis to prevent oscillation near cutoff - protecting Li-ion cells from deep discharge damage while allowing controlled restart once voltage recovers.

What thermal protection mechanisms are implemented?

The MP2710GC-0000-Z features two-tier thermal protection: (1) thermal regulation at 120°C (adjustable via register), which linearly reduces charge current to hold junction temperature constant, and (2) hard thermal shutdown at 150°C with 20°C hysteresis - both monitored continuously and reported via I²C status registers.
