The EV2672 Evaluation Board is designed to demonstrate the capabilities of MPS’ MP2672.

The MP2672 is a high-integrated, flexible switch-mode battery charging management device for 2-cell series Li-ion and Li-Polymer battery pack used in a wide range of portable applications.

When 5V adapter or USB input is present, the MP2672 charges 2-cell battery in step-up mode, when 5V input is absent, 2-cell battery discharges and the battery supplies system. 

For the charging function in each application, the MP2672 automatically detects the battery voltage and charges the battery in the three phases: pre current, constant current and constant voltage. Other features include charge termination and auto-recharge.

To guaranteed safe operation, the MP2672 limits the die temperature to a preset value 120ºC. Other safety features include input overvoltage protection, battery over-voltage protection, thermal shutdown, battery temperature monitoring, and a programmable timer to prevent prolonged charging of a dead battery.
