Product Details

The MAX1879, in conjunction with a P-channel MOSFET and a current-limited wall-mount adapter with an output voltage between +4.7V to +20V, allows safe and quick charging of a single lithium-ion (Li+) cell.

The MAX1879 evaluation kit (EV kit) is a complete, fully assembled and tested Li+ battery charger. Jumpers on the EV kit allow easy adjustment to a +4.1V or +4.2V battery regulation voltage. A light-emitting diode (LED) indicates the cell's charging status.

Applications

Cell Phones
Consumer Audio
Cordless Phones
Digital Still Cameras
Global Positioning Systems (GPS)
Pagers
Palmtops, Handy Terminals
Pen Entry Palmtops, PDAs and Organizers
Smart Battery Packs/Chargers
