Monolithic Power Systems (MPS) EV2723-QC-00A Evaluation Board

Monolithic Power Systems (MPS) EV2723-QC-00A Evaluation Board is designed to demonstrate the capabilities of the MP2723 Switch-Mode Battery Charger IC. The MP2723 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 MP2723 to be easily controlled. The MP2723 is ideal for use with single-cell Li-ion or Li-polymer batteries.

The Monolithic Power Systems (MPS) EV2723-QC-00A Evaluation Board features a pre-installed MP2723 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.
