Monolithic Power Systems Inc. MP2710GC-0001-Z

Overview

MP2710GC-0001-Z 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 enables simultaneous system powering and battery charging in space-constrained portable devices such as TWS earbuds and smartwatches.

For engineers reviewing the MP2710GC-0001-Z datasheet, MP2710GC-0001-Z pinout, MP2710GC-0001-Z application, or MP2710GC-0001-Z equivalent, key selection considerations include configurable I²C-based 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 hardware-triggered shipping mode entry.

Technical Context

The MP2710GC-0001-Z implements a dual-MOSFET power-path architecture: a 290mΩ LDO from IN to SYS and a 100mΩ NMOS from BATT to SYS, enabling priority-based system load delivery independent of charge current. Its I²C interface controls 8-bit fast-charge current (8–456mA), 6-bit battery regulation voltage (3.6V–4.53V), and 4-bit input current limit (50–500mA).

It integrates autonomous charge sequencing-pre-charge (configurable 1–31mA), CC, CV, 1mA termination with 3.2s deglitch, auto-recharge at 60–240mV below VBATT_REG-and robust protection including input OVP (6V), UVLO (3.25V), battery UVLO (2.4–3.13V), thermal regulation (120°C), and shutdown (150°C).

FAQ

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

The INT pin serves a dual function: it asserts open-drain status/fault signals (e.g., charge complete, thermal alert) to the host processor, and-when driven low by the host-forces immediate disconnection of the battery from the SYS rail. This hardware-controlled isolation is critical for safety-critical shutdowns and shipping mode activation without I²C communication.

How does the MP2710GC-0001-Z handle input current limiting during system load transients?

When system load current exceeds available input current (IIN_LIMIT), the MP2710GC-0001-Z automatically reduces charge current (ICHG) to zero and supplements the deficit using battery current via the 100mΩ BATT→SYS FET. This maintains stable VSYS without brownout, even under sudden 0A→1A load steps, as verified in SYS load transient test waveforms.

Can the battery UVLO threshold be adjusted, and what are the valid settings?

Yes-the battery UVLO threshold is configurable via REG01h[2:0] and offers three factory-set options: 2.40V (000), 2.76V (100), and 3.03V (111). These correspond to standard Li-ion cutoff voltages for different cell chemistries and aging profiles, enabling optimization for cycle life versus runtime in final product calibration.

What is the role of the EN_HIZ bit in power-path control?

Setting EN_HIZ = 1 places the IN→SYS LDO MOSFET in high-impedance (Hi-Z) state, effectively disconnecting the input source from the system rail. This allows clean system power-up solely from battery-even if VIN is present-enabling controlled boot sequences and eliminating backfeed risks during hot-plug events.

Does the MP2710GC-0001-Z support charging from a 9V input source?

No-the MP2710GC-0001-Z is rated for 4.35V–5.5V operating input voltage and has an absolute maximum VIN of 21V, but its internal LDO architecture and input current limit circuitry are optimized for 5V sources only. Using 9V input would exceed the 5.5V operating range and trigger immediate VIN_UVLO or OVP shutdown.

How is thermal regulation implemented, and does it affect system voltage stability?

Thermal regulation activates at 120°C (TJ_REG) by linearly reducing ICHG to maintain die temperature-distinct from thermal shutdown at 150°C. VSYS remains tightly regulated (±100mV) during regulation because the IN→SYS LDO and BATT→SYS FET operate independently; only charge current is throttled, not system power delivery.

Is the NTC interface compatible with common 10kΩ NTC thermistors?

Yes-the NTC pin provides a 50µA bias current and accepts standard 10kΩ @25°C NTCs. The datasheet specifies voltage thresholds (e.g., 1050mV cold, 233mV warm) corresponding to industry-standard Beta values (3380K–3950K), eliminating need for external resistor dividers and simplifying layout in size-sensitive designs.
