Monolithic Power Systems (MPS) EV2731-QC-00A Evaluation Board

Monolithic Power Systems (MPS) EV2731-QC-00A Evaluation Board is designed to demonstrate the capabilities of the MP2731 Switch-Mode Battery Charger IC. The MP2731 works with NVDC system power path management and supports USB On-The-Go (OTG) operation. The device's low-impedance power path optimizes efficiency, reduces battery charging time, and extends battery life. The I²C serial interface allows the charging and system settings of the MP2731 to be easily controlled. The MP2731 is ideal for use with single-cell Li-ion or Li-polymer batteries.

The Monolithic Power Systems (MPS) EV2731-QC-00A Evaluation Board features a pre-installed MP2731 in a QFN-26 package. The Evaluation Board is designed to connect to the EVKT-USBI2C-02 USB to I²C/PMBus Dongle (not included), which in turn connects to a Microsoft Windows-based PC. An I²C Graphic User Interface (GUI) provides an easy-to-use interface for demonstrating the features of the MP2731 Battery Charger IC.
