Product Description

The MP2612 is a monolithic switching charger for 2-, 3- series Li-Ion cells battery with a built in internal power MOSFET. It achieves up to 2A charge current with current mode control for fast loop response and easy compensation. The charge current can be programmed by sensing the current through an accurate sense resistor. MP2612 regulates the battery voltage and charge current using two control loops to realize high accuracy CC charge and CV charge. Fault condition protection includes cycle-­by­-cycle current limiting and thermal shutdown. Other safety features include battery temperature monitoring, charge status indication and programmable timer to finish the charging cycle. The MP2612 requires a minimum number of readily available standard external components. The MP2612 is available in 16-pin QFN package.
