1.1MHz Switching Li-Ion Charger, up to 90% Efficiency



The MP2610 is a monolithic switching charger for 1 or 2 cells Li-Ion battery packs 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. MP2610 regulates the charge current and charger voltage 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 cease the charging cycle. The MP2610 requires a minimum number of readily available standard external components. The MP2610 is available in 4mm×4mm 16-pin QFN package.
