28V, 1A Li-Ion/Li-Polymer Battery Charger with Trickle Charge and Timer



The MP2605 is a linear, high performance single cell Li-Ion/Li-Polymer battery charger. By integrating high voltage input protection into the charger IC, the MP2605 can tolerate an input surge up to +28V and a reverse input voltage to -16V. The device features constant current (CC) and constant voltage (CV) charging modes with programmable charge currents (200mA to 1A), current blocking, and trickle charge. The device also provides fault and charge status indications to the system. For guaranteed safe operation, the MP2605 reduces charge current when the device reaches high temperature (due to limited PCB space). Other safety features include battery temperature monitoring and programmable timer to complete the charging cycle. The MP2605 is available in 10-pin 3mm x 3mm QFN packages.
