EV2672A-D-00B

Evaluation board designed to demonstrate the capabilities of the MP2672A. The MP2672A is a highly integrated, flexible, switch-mode battery charging management device for 2-cell series Li-ion and Li-polymer battery packs. The MP2672A can be used in a wide range of portable applications. When a 5V adapter or USB input is present, the MP2672A charges the 2-cell battery in step-up mode. 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 over-voltage protection (OVP), battery OVP, thermal shutdown, battery temperature monitoring, and a configurable timer to prevent prolonged charging of a dead battery.
