Li-Ion/Li-Polymer battery charger IC

14 October 2009 Power Electronics / Power Management

The P2607 from Monolithic Power Systems is a highly-integrated single-cell Li-Ion/Li-Polymer battery charger with a system power path management function. It takes input from either an AC adapter or a USB port to supply the system and charge the battery independently. The charger section features trickle charge, high-accuracy constant current (CC) and constant voltage (CV) regulation, charge termination and charge status.

The system power path management function ensures continuous supply to the system by automatically selecting the input, the battery or both to power the system. This section features a low dropout regulator from input to system, and a 50 m switch from battery to system. Power path management separates charging current from system load, which allows proper charge termination and keeps the battery fully charged. It also allows instantaneous power-up of a system with a deeply discharged battery. The MP2607 is available in a 14-pin 3 x 4 mm QFN package.
