Monolithic Power Systems Inc. MP2760GVT-000A-Z

Overview

MP2760GVT-000A-Z from Monolithic Power Systems is an I²C-controlled buck-boost battery charger IC supporting 1–4 series Li-ion/Li-polymer cells, featuring NVDC power path management, 4V–22V input range, up to 6A charge current, and USB PD 3.0 compliance for ultrabook and tablet power systems.

For engineers reviewing the MP2760GVT-000A-Z datasheet, MP2760GVT-000A-Z pinout, MP2760GVT-000A-Z application, or MP2760GVT-000A-Z equivalent, this page delivers verified specifications, TQFN-30 package layout, thermal regulation thresholds, I²C-configurable charge/source parameters, and real-world use cases in portable computing and USB-C PD devices.

Technical Context

The MP2760 implements a synchronous four-switch buck-boost topology with integrated N-channel MOSFET drivers (ACGATE, BGATE), enabling seamless transition between buck and boost modes while maintaining regulated system voltage (VSYS_MIN) independent of battery state. It supports dual-role operation: charging from adapter input (4V–22V) and sourcing power to system (4V–21V) via IN pin.

Its embedded 10-bit ADC monitors battery current (via TS/IMON), temperature (NTC/VNTC), and input/battery voltages, feeding real-time data to I²C/SMBus registers. Safety logic enforces JEITA-compliant thermal thresholds, configurable OVP/UVP on ADP, VIN, SYS, and VBATT, plus battery missing and NTC floating detection.

FAQ

What does the "-000A" suffix indicate in MP2760GVT-000A-Z?

The "-000A" suffix denotes the factory-default configuration for 2-cell battery applications, pre-programmed with OTP settings for 6.8–9.36V battery regulation, 6.4V minimum system voltage, and JEITA cold/cool/warm/hot thresholds aligned to common NTC thermistor curves.

How is NVDC power path implemented without external components?

NVDC is enabled via the integrated BGATE driver controlling an external N-channel MOSFET between SYS and BATT pins. The IC regulates VSYS_MIN independently using feedback from the SYS pin, allowing system operation even when VBATT falls below operational voltage.

Can MP2760GVT-000A-Z operate in source mode without battery presence?

No. The device requires a valid battery connection (VBATT > 2.6V/cell) to enable source mode. Battery UVLO detection disables all power path functions if voltage drops below threshold, preventing unsafe unregulated sourcing.

What is the role of the TS/IMON pin in charge versus source mode?

In charge mode, TS/IMON outputs an analog voltage proportional to battery charging current (±1% gain error). In source mode, it reflects discharging current magnitude, enabling real-time battery discharge monitoring without additional sense resistors.

How does the MP2760 handle USB PD voltage negotiation?

The MP2760 itself does not perform PD communication; it relies on an external PD controller (e.g., CYPD3177). That controller writes negotiated voltage/current limits into MP2760 registers (e.g., REG09h for VIN_SRC), which the IC then enforces via its internal DAC and regulation loop.

Is thermal regulation distinct from thermal shutdown?

Yes. Thermal regulation (configurable up to 120°C) reduces switching frequency and charge current to maintain die temperature below threshold. Thermal shutdown (150°C, 20°C hysteresis) forces complete power-down only if regulation fails, providing layered protection.

What package-level thermal performance can be expected on a 4-layer PCB?

With proper thermal pad soldering and copper pour, θJA is 38°C/W. At 3.29W max dissipation (TA=25°C), junction temperature rises ~125°C above ambient-confirming need for thermal regulation activation before reaching 150°C shutdown.
