The EV2664-G-00A is an evaluation board for the MP2664, a highly integrated, single-cell Li-ion/Li-polymer battery charger with system power path management, designed for space-limited portable applications. It takes input power from either an AC adapter or a USB port to supply the system load and charge the battery independently. The charger section features constant-current pre-charge (PRE.C), constant-current fast charge (CC) and constant voltage (CV) regulation, charge termination, and charge status.

The EV2664 ensures that there is continuous power to the system by automatically selecting the input, the battery, or both to power the system. It provides system short circuit protection to prevent the Li-Ion battery from being damaged due to excessive high current. The EV2664 cuts off the path between the battery and system when battery UVLO is reached to prevent the Li-Ion battery from being overly discharged.

Through the I²C connector on the EV2664, the user can program the charging parameters, such as the input current limit, input minimum voltage regulation, charging current, battery regulation voltage, and battery UVLO.
