The MAX1757/MAX1758 evaluation kits (EV kits) are

assembled and tested PC boards that implement a

step-down, switching lithium-ion (Li+) battery charger.

The MAX1757 EV kit can be set to charge 1- to 3-series

cells, and the MAX1758 EV kit can be set to charge 1-

to 4-series cells. The cell voltage can be set between

4.0V and 4.4V using standard 1% resistors while main-

taining 1% overall regulation voltage accuracy. Three

LEDs indicate the charging status.

The MAX1757/MAX1758 EV kits detect faulty cells and

terminate charging. Two capacitors are used to set the

charge termination, prequalification, and fault timeout

periods. A user-supplied thermistor may be connected

to either EV kit to monitor battery temperature and sus-

pend charging for over-/undertemperature conditions.
