Monolithic Power Systems Inc. MP2710GC-0001-P

Overview

MP2710GC-0001-P 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 WLCSP-9 packaging. It delivers simultaneous system power and battery charging for space-constrained portable devices such as TWS earbuds and smartwatches.

For engineers reviewing the MP2710GC-0001-P datasheet, MP2710GC-0001-P pinout, MP2710GC-0001-P application, or MP2710GC-0001-P equivalent, key selection considerations include configurable I_{IN_LIMIT} (50–500mA), ±0.5% battery voltage regulation accuracy, thermal regulation at 120°C, JEITA-compliant temperature profiling, and hardware-triggered shipping mode entry via the INT pin.

Technical Context

The MP2710GC-0001-P implements dual-MOSFET power-path architecture: a 290mΩ LDO switch (IN→SYS) and a 100mΩ battery FET (BATT→SYS), enabling priority-based system load delivery while decoupling charge current from system current. Its I²C interface configures all critical parameters-including I_{IN_LIMIT}, V_{BATT_REG} (3.6V–4.53V), V_{SYS_REG} (4.2V–4.95V), and pre-charge/fast-charge currents-without external resistors.

It integrates robust protection including input OVP (6.0V typ), battery UVLO (configurable 2.4V–3.13V), thermal shutdown (150°C), watchdog timer (160s), and NTC-based JEITA profile control with no external resistor divider required. The device supports auto-recharge (60–240mV below V_{BATT_REG}) and enters <350nA shipping mode via hardware trigger on INT pin.

FAQ

What distinguishes MP2710GC-0001-P from the MP2710GC-0000 variant?

The MP2710GC-0001-P is factory-configured for hardware-triggered shipping mode entry via the INT pin, whereas MP2710GC-0000 uses I²C register write only. Both share identical electrical specs and WLCSP-9 packaging, but MP2710GC-0001-P enables zero-firmware shipping mode activation-critical for pre-programmed consumer devices shipped in powered-off state.

Does MP2710GC-0001-P require external NTC biasing resistors?

No. The MP2710GC-0001-P integrates a precision 50µA NTC bias current source, eliminating the need for external resistor dividers. This reduces BOM cost, PCB area, and battery current consumption-unlike alternatives such as BQ25618 that require external bias networks for accurate temperature sensing.

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

The MP2710GC-0001-P prioritizes system load: when input current (I_IN) is limited, it automatically reduces charge current (I_CHG) to maintain regulated V_SYS. If I_IN is insufficient, the 100mΩ battery FET supplements power-ensuring uninterrupted operation without forcing premature battery discharge or unsafe charge interruption.

What is the minimum battery voltage at which MP2710GC-0001-P resumes charging after auto-recharge?

Auto-recharge initiates when battery voltage falls 60–240mV below the configured V_{BATT_REG}, depending on register REG04h[0] setting. For example, with V_{BATT_REG} = 4.2V and REG04h[0] = 0, recharge starts at ~4.1V; with REG04h[0] = 1, it starts at ~4.0V-preventing deep discharge while avoiding excessive cycling.

Can MP2710GC-0001-P operate without an NTC thermistor?

Yes. The NTC function is optional: if unused, the NTC pin can be left floating or tied to GND. The device operates full-featured charging without NTC, but JEITA temperature profiling and cold/hot charge inhibition will be disabled-suitable for indoor-use devices where ambient temperature remains within safe Li-ion limits.

What thermal protections are implemented beyond junction shutdown?

In addition to 150°C thermal shutdown, MP2710GC-0001-P features programmable thermal regulation at 120°C (default), which linearly reduces charge current to hold die temperature constant. It also includes watchdog monitoring via I²C to detect firmware lockup and force safe recovery-providing layered protection unmatched by basic chargers.

Is the 100mΩ battery FET rated for continuous discharge current?

Yes-the integrated 100mΩ battery FET supports up to 3.2A continuous discharge current (per REG0Dh settings), enabling direct drive of high-pulse loads like Bluetooth radios or optical sensors without external MOSFETs. Its R_DS(on) is characterized across -40°C to +125°C for reliable performance in wearable thermal envelopes.
