Monolithic Power Systems Inc. MP2710GC-0000-P

Overview

MP2710GC-0000-P from Monolithic Power Systems is a single-cell Li-ion/Li-polymer battery charger IC with integrated power-path management (PPM), I²C programmability, 456mA max charge current, ±0.5% battery voltage regulation accuracy, and <350nA battery leakage in shipping mode. It delivers simultaneous system power and battery charging for compact portable devices such as TWS earbuds and smartwatches.

For engineers reviewing the MP2710GC-0000-P datasheet, MP2710GC-0000-P pinout, MP2710GC-0000-P application, or MP2710GC-0000-P equivalent, key selection considerations include configurable I²C charge parameters (ICHG, VBATT_REG, VIN_MIN), dual-path PPM architecture with 290mΩ IN→SYS LDO and 100mΩ BATT→SYS switch, JEITA-compliant thermal protection, and shipping-mode entry/exit control via I²C or analog pin.

Technical Context

The MP2710GC-0000-P implements a dual-MOSFET power-path architecture: a 290mΩ LDO from IN to SYS and a 100mΩ NMOS from BATT to SYS, enabling independent control of system supply and battery charging. Its I²C interface configures 8–456mA charge current in 2mA steps, 3.6V–4.53V battery regulation voltage, and 3.88V–5.08V minimum input regulation voltage.

It integrates pre-charge, CC/CV charging, 1mA termination, auto-recharge at 60–240mV below VBATT_REG, and robust protections including input OVP (6V), UVLO (3.25V), battery UVLO (configurable 2.4V–3.13V), thermal regulation (120°C), and shutdown (150°C). The NTC bias current is fixed at 50µA, eliminating external resistor divider current draw.

FAQ

What is the function of the INT pin beyond interrupt signaling?

The INT pin serves a dual role: it outputs open-drain status/fault signals (e.g., charge complete, thermal fault) and functions as a hardware-controlled switch enable for the BATT→SYS MOSFET. Pulling INT low disconnects the battery from the system, enabling controlled system reset or shipping mode exit-eliminating need for separate reset circuitry.

How does the MP2710GC-0000-P handle input current limiting during system load transients?

When system load exceeds available input current (IIN_LIMIT), the MP2710 dynamically reduces charge current (ICHG) to zero and engages the 100mΩ BATT→SYS switch to supplement power. This maintains stable VSYS without brownout, while preserving battery health via precise current control and thermal regulation.

Can the NTC interface operate without external components?

Yes-the MP2710GC-0000-P provides a precise 50µA internal NTC bias current, allowing direct connection of a single NTC thermistor to the NTC pin. No external resistor divider is required, removing ~10µA of continuous battery drain and simplifying layout in tight spaces.

What defines "shipping mode" and how is it exited?

Shipping mode disables all internal regulators except the I²C interface and reduces battery leakage to <350nA. It can be entered via I²C command (REG06h[5]=1) or by asserting the dedicated hardware pin. Exit occurs automatically upon VIN plug-in (with 80ms deglitch) or by pulling INT low for 2 seconds.

Is the 100mΩ BATT→SYS MOSFET rated for continuous discharge?

Yes-the integrated battery FET supports up to 3.2A continuous discharge current (configurable via REG0Dh), with thermal regulation active above 120°C. Its 100mΩ R_DS(on) ensures <30mV dropout at 300mA, minimizing voltage loss during system startup from depleted batteries.

How does the MP2710GC-0000-P ensure accurate charge termination with varying temperatures?

Charge termination uses a 3.2-second deglitch timer and configurable 1–31mA threshold (REG03h[3:0]). The ±0.5% VBATT_REG accuracy and thermal regulation maintain consistent CV phase behavior across -40°C to +125°C, preventing premature cutoff or overcharge due to voltage drift.

Does the WLCSP-9 package support automated optical inspection (AOI)?

Yes-the MP2710GC-0000-P's WLCSP-9 (1.85mm × 1.85mm, 0.4mm pitch) features solder balls with defined coplanarity and IPC-7351B-compliant land patterns, enabling reliable AOI detection of solder joint integrity, voiding, and alignment in high-volume SMT lines.
