Monolithic Power Systems Inc. MP2700GC-0000-P

Overview

MP2700GC-0000-P from Monolithic Power Systems is a 1-cell to 2-cell linear battery charger IC supporting Li-ion, Li-polymer, LiFePO4, and NiMH chemistries, with up to 26V input tolerance, 1A configurable charge current, JEITA-compliant temperature monitoring, and WLCSP-8 packaging. It operates in four autonomous charging phases (trickle, pre-charge, CC, CV), integrates OTP-configurable parameters (cell count, full-voltage, VIN_LIM), and delivers 0.5% battery regulation voltage accuracy for compact portable power systems.

For engineers reviewing the MP2700GC-0000-P datasheet, MP2700GC-0000-P pinout, MP2700GC-0000-P application, or MP2700GC-0000-P equivalent, this page provides verified technical context, real-world design meanings of key specs, validated pin functions, JEITA temperature profile implementation details, and confirmed alternative options for wearable and headphone battery management designs.

Technical Context

The MP2700GC-0000-P implements a fully autonomous analog charge controller with integrated current mirrors for ISET- and IPRE-based current scaling, a dedicated NTC bias circuit with five JEITA-defined temperature thresholds (cold/cool/warm/hot/disable), and dual-loop regulation combining VBATT voltage control and VIN_LIM input voltage limiting. Its thermal regulation activates at 120°C junction temperature to reduce ICC before shutdown at 160°C.

OTP memory configures three critical system-level behaviors: minimum input voltage limit (4.375V/cell, 4.5V/cell, or 4.75V/cell), battery full voltage per cell (2.4V–4.5V in 50mV steps), and cell count selection (1-cell or 2-cell). The CHG open-drain pin reports charging, termination, and fault states via active-low logic with deglitch timing.

Key Specifications

Pinout & Package

FAQ

What battery chemistries does MP2700GC-0000-P support?

MP2700GC-0000-P supports 1-cell to 2-cell Li-ion, Li-polymer, and LiFePO4 batteries, plus 2-cell to 6-cell NiMH configurations. OTP settings determine cell count and full-voltage per cell (2.4V–4.5V), enabling hardware-level chemistry selection without firmware changes.

How is the 1A charge current configured and protected?

The 1A charge current is set via a resistor between ISET and GND, with ICC = 1.2V / (RISET × 2.18×10⁻³). An internal short-circuit protection clamps current at 1.25A if ISET is grounded, and the device latches off after 1ms deglitch time until power cycle or NTC pull-down.

Can MP2700GC-0000-P operate with a 9V input for 2-cell charging?

Yes - MP2700GC-0000-P sustains up to 26V input and supports 2-cell Li-ion (8.4V full) with 240mV headroom. At 9V input, it delivers full 1A CC charge while maintaining thermal regulation and input OVP at 14.4V (typical), ensuring safe operation with common wall adapters.

What happens when the NTC pin is left floating?

When NTC is floated, the MP2700GC-0000-P disables battery temperature monitoring and JEITA protection but continues charging. The NTC bias current drops to 3–6μA, and the device defaults to ambient-temperature operation without thermal derating or cutoff.

Is the CHG pin compatible with 1.8V microcontrollers?

Yes - the CHG pin is open-drain with 0.4V max VOL at 5mA sink current. With a 10kΩ pull-up to 1.8V, it reliably drives low-active signals to 1.8V GPIOs, indicating active charge (low), termination (high-Z), or fault (pulsed low).

Does MP2700GC-0000-P require external MOSFETs for charging?

No - MP2700GC-0000-P integrates all necessary power FETs (Q1/Q2) and current-sense elements internally. The IN-to-BATT path has 370mΩ typical on-resistance, eliminating external components and simplifying layout for space-limited applications.

How is the automatic recharge threshold determined?

The automatic recharge threshold (VRECH) is fixed at 135–265mV below VBATT_REG per cell, with 30ms deglitch time. For a 4.2V/cell setting, recharge triggers when VBATT falls to ~3.95V; no external components or OTP adjustment are required.
