EV2672A-D-00A

Evaluation board designed to demonstrate the capabilities of MP2672A. The MP2672A 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 MP2672A charges 2-cell battery in step-up mode, when 5V input is absent, 2-cell battery discharges and the battery supplies system. To effectively charge each application, the MP2672A automatically detects the battery voltage and charges the battery in three phases: pre-charge, constant current (CC) charge, and constant voltage (CV) charge. Other charging features include charge termination and auto-recharge. To guarantee safe operation, the MP2672A limits the die temperature to a pre-set value (about 120°C). Other safety features include input OVP, battery OVP, thermal shutdown, battery temperature monitoring and a configurable timer to prevent prolonged charging of dead battery.
