MAX1898 Evaluation Kit

General Description

Features

ꢀ Simple Stand-Alone Li+ Charger

The MAX1898 evaluation kit (EV kit) is a complete, fully

assembled and tested single-cell lithium-ion (Li+) bat-

tery charger. The EV kit charges a single Li+ battery to

4.2V using a power supply with an output voltage of

4.7V to 12V. At input voltages greater than 6V, the

allowed charging current may be limited by the power-

dissipation rating of the external MOSFET. Jumpers on

the EV kit allow simple adjustment to the total charging

time and charger restart voltage levels. An LED indi-

cates the cell’s charging status. To charge a Li+ battery

to 4.1V, replace the MAX1898 (U1) IC on the EV kit

board with the MAX1898EUB41.
