The EV2672A-D-00A is an evaluation board is designed to demonstrate the capabilities of the MP2672A, a highly integrated, flexible switch-mode battery charger IC for Li-ion or Li-Polymer batteries with two cells in series. This makes the MP2672A applicable for a wide range of portable applications.
If the input power (5V adapter or USB input) is present, the MP2672A operates in boost mode to charge the battery with two cells in series. If the 5V input is absent, the 2-cell battery discharges and the battery FET supplies power to the system.
When charging is enabled, the MP2672A automatically detects the battery voltage and charges the battery in three phases: pre-charge, constant-current charge, and constant-voltage charge. Other features include charge termination and auto-recharge.
To guarantee safe operation, the MP2672A limits the die temperature to a preset value of 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. The MP2672A is available in a QFN-18 (2mmx3mm) package.
