MAX1879 Evaluation Kit
General Description
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鈥檚 charging status. A 6VDC, current-
limited wall-mount cube that supplies 400mA of con-
stant current is included with the kit.
