Monolithic Power Systems Inc. EV2760-VT-00A

Overview

EV2760-VT-00A from Monolithic Power Systems is an I²C-controlled evaluation board for the MP2760 buck-boost narrow-voltage DC (NVDC) charger IC, designed to demonstrate 1-cell to 4-cell Li-ion battery charging and reverse-source (OTG) operation in portable power systems. It supports 4V–22V input, delivers up to 6A charge current, enables 3V–21V source-mode output, and integrates full NVDC power path management with real-time GUI-based configuration via USB-to-I²C interface.

For engineers reviewing the EV2760-VT-00A datasheet, EV2760-VT-00A pinout, EV2760-VT-00A application, or EV2760-VT-00A equivalent, this board provides validated reference design, thermal performance data, efficiency curves across charge/source modes, and register-level control of battery regulation voltage (8.4V), switching frequency (600 kHz), and safety timers - all critical for USB PD-compliant portable electronics development.

Technical Context

The EV2760-VT-00A implements the MP2760's dual-mode architecture: in charge mode, it dynamically selects buck or buck-boost topology based on VIN vs. VBATT; in source mode, it reverses power flow from battery to IN pin with programmable VIN_SRC (4.98V default) and IIN_SRC limit (2A). The board uses a 1.5μH MPS inductor (MPL-AL5030-1R5) and TQFN-30-packaged MP2760GVT-000A IC to achieve 96% peak efficiency in both modes.

It features hardware-configurable jumpers (JP1 for VCC/EXT bias, JP2 for TS/IMON selection), dedicated test points for VIN, VBATT, VSYS, and VIN_SRC, and supports real-time monitoring of ADC-measured voltages, currents, and temperatures via the MP2760 Evaluation Software on Windows 7/10. All register settings-including JEITA thermal profiles, PPM thresholds, and watchdog timer-are modifiable through the GUI.

FAQ

What software is required to operate the EV2760-VT-00A?

The MP2760 Evaluation Software (Windows 7/10 compatible) is mandatory and must be installed before connecting the EVKT-USBI2C-02 USB-to-I²C kit. It provides full register access, real-time monitoring of VBATT, VSYS, VIN_SRC, and fault status, and supports parameter sweeps for JEITA, PPM, and watchdog configurations - no command-line tools or third-party drivers are needed.

Does the board support 3-cell or 4-cell battery configurations out of the box?

Yes - the MP2760GVT-000A on the board is factory-configured for 2-cell operation but supports 1–4 cells via I²C register writes. The GUI's "General Settings" tab allows immediate reconfiguration of cell count, battery-full voltage (e.g., 12.6V for 3-cell), and corresponding pre-charge/recharge thresholds without hardware modification.

Can the EV2760-VT-00A be used to validate thermal performance under sustained source-mode load?

Yes - the board includes thermal test points and uses the same 1.5μH MPL-AL5030-1R5 inductor and SISA14DN-T1-GE3 MOSFET as production designs. Published thermal images show <15°C junction rise at VBATT=8.4V, VIN_SRC=20V, IIN_SRC=1.8A - enabling direct correlation to end-equipment thermal modeling.

Is external hardware required to interface with the evaluation software?

Yes - the EVKT-USBI2C-02 USB-to-I²C communication kit is mandatory. It connects via standard USB-A cable to the host PC and interfaces with the EV2760-VT-00A's SCL/SDA pins through JP1 header. No additional level shifters or debug probes are needed - the kit handles 3.3V logic translation and I²C clock stretching natively.

How are current-sense resistors configured on this board?

The board populates four precision shunts: R7/R8/R16/R27 (20mΩ, 1206) for battery current sensing, and R9 (1mΩ, 0603) for input current monitoring. The GUI's "Current-Sense Resistor Settings" page lets users select active shunt paths and calibrate gain values - matching actual resistor tolerances and PCB trace parasitics for ±1.5% current measurement accuracy.

What protection features can be validated using this evaluation board?

All MP2760 protections are fully accessible: input UV/OV lockout (configurable thresholds), battery OVP (8.6V default), JEITA thermal zone enforcement, safety timer extension, and source-mode overcurrent shutdown. Fault status registers (e.g., FAULT_INT, SRC_FAULT) are readable in real time via the GUI's "Fault Settings" tab and trigger visible LED alerts on the board.

Does the board include provisions for external NTC thermistors?

Yes - the NTC pin is routed to a dedicated header (NTC) with configurable pull-up/pull-down options. The GUI's "NTC JEITA Settings" page allows full definition of temperature zones, hysteresis, and trip thresholds - validated using standard 10kΩ NTCs (e.g., Murata NCP15XH103D03RC) per JEITA-57020 standards.
