Monolithic Power Systems Inc. MP2760GVT-0000-P

Overview

MP2760GVT-0000-P from Monolithic Power Systems is a fully integrated I²C-controlled buck-boost battery charger supporting 1–4 series Li-ion/Li-polymer cells, delivering up to 6A charge current with ±0.5% battery voltage regulation accuracy, NVDC power path management, and USB PD 3.0-compliant source mode (4V–21V, up to 6A) for ultrabooks and portable USB-C devices.

For engineers reviewing the MP2760GVT-0000-P datasheet, MP2760GVT-0000-P pinout, MP2760GVT-0000-P application, or MP2760GVT-0000-P equivalent, key selection considerations include configurable input current limit (0–5.8A), programmable battery full voltage (up to 4.68V/cell), thermal regulation threshold (configurable up to 120°C), NVDC system voltage setting (3.53V–12.36V), and I²C-accessible fault registers for real-time status monitoring.

Technical Context

The MP2760 implements a synchronous 4-switch buck-boost topology with integrated power MOSFETs (RON_Q1 = 10 mΩ, RON_Q2 = 8 mΩ, RON_Q3 = 8 mΩ, RON_Q4 = 20 mΩ), enabling seamless transition between buck and boost modes across 4V–22V input and battery voltages that may lie above or below VIN. It integrates dual gate drivers (ACGATE for input pass-through MOSFET, BGATE for BATFET) and supports both charge and bidirectional source modes via register-controlled state machine.

Its embedded 10-bit ADC monitors battery current (via TS/IMON), NTC thermistor voltage (VNTC), and adapter voltage (ADP), while safety logic enforces JEITA-compliant temperature thresholds, configurable timers (e.g., 20-hour max charge), and multiple OVP/UVP protections on IN, SYS, BATT, and VIN_SRC rails - all accessible and modifiable through I²C/SMBus registers (e.g., REG0Eh for fSW, REG07h for VSYS_MIN, REG10h for VTRACK).

FAQ

What is the maximum sustainable input voltage for MP2760GVT-0000-P?

The MP2760GVT-0000-P supports up to 22V continuous input voltage (VIN), with absolute maximum rating of 26V on IN and 28V on ADP with external MOSFET. Its ADP OVP threshold is factory-set at 23.9V (typical), triggering shutdown if exceeded - ensuring robust protection against transient overvoltage events in USB PD and adapter applications.

How does NVDC power path management operate during adapter removal?

When the adapter is removed, the MP2760GVT-0000-P uses the BATFET (controlled by BGATE) to maintain SYS voltage above the configured minimum (e.g., 6.4V for 2-cell). The IC continuously monitors SYS and regulates battery discharge to prevent system brownout, enabling uninterrupted operation during hot-swap battery replacement or brief adapter disconnection.

Can MP2760GVT-0000-P be used without an external NTC thermistor?

Yes - the NTC circuit can be disabled via register (REG0Dh bits[1:0] = 00), and the TS/IMON pin repurposed for current monitoring. However, battery temperature protection is then inactive, and JEITA compliance is lost. For safety-critical applications, MPS recommends retaining NTC with proper biasing via VNTC and NTC pins per datasheet Figure 10.

What is the role of the ACGATE pin and what external component is required?

The ACGATE pin drives the gate of an external N-channel MOSFET placed between ADP and IN to implement input over-voltage protection and enable smooth adapter-to-battery switchover. A 1MΩ resistor must be connected between ACGATE and the MOSFET source; the MOSFET must support ≥28V VDS and low RDS(on) (e.g., <10mΩ) to minimize conduction loss during high-current operation.

Does MP2760GVT-0000-P support charging from a 5V USB-A source?

Yes - the 4V–22V input range includes standard 5V USB-A adapters. When used with 5V input, the MP2760GVT-0000-P operates in boost mode for 2S+ batteries (e.g., 7.4V nominal), delivering up to 6A charge current with efficiency >90% at mid-SOC. Input current limiting (IIN_LIM) must be configured to avoid exceeding source capability.

How is battery full voltage configured, and what is its accuracy?

Battery full regulation voltage is set via I²C register REG10h (bits[10:9] for cell count, bits[4:0] for voltage step), supporting up to 4.68V/cell in 20mV increments. Accuracy is ±0.5% at 25°C and ±0.7% over 0°C–70°C - verified across 1S–4S configurations and traceable to internal bandgap reference.

Is there a recommended evaluation board for MP2760GVT-0000-P?

Yes - the EVKT-MP2760 evaluation kit includes the EV2760-VT-00A board, USB-to-I²C interface (EVKT-USBI2C-02), GUI software, and documentation. It supports full register access, real-time telemetry (V/I/T), and validation of charge/source modes, NVDC transitions, and fault responses per Rev. 1.2 datasheet test conditions.
