Product Description

The MP26028 is a linear, high performance single cell Li-Ion battery charger. By integrating high voltage input protection into the charger IC, the MP26028 can tolerate an input surge up to 20V. The device features constant current (CC) and constant voltage (CV) charging modes with programmable charge currents (85mA to 1A), programmable battery full threshold, thermal protection, battery temperature monitoring, reverse current blocking, and trickle charge. The device also provides AC adapter power good and charge status indications to the system. MP26028 is available in a 10-pin 3mm x 3mm QFN package.
