Description

The MAX1507/MAX1508 evaluation kit (EV kit) is a complete, fully assembled, and tested circuit board that demonstrates the MAX1507 linear battery charger for a single-cell lithium-ion (Li+) battery. To evaluate the MAX1508, U1 must be removed and replaced with a MAX1508 device. The EV kit safely charges a single Li+ battery to 4.2V. The EV kit accepts a power-supply input of 4.25V to 13V, but disables charging when the input voltage exceeds 7V. Jumpers on the EV kit allow adjustments to the die-temperature regulation levels (MAX1507 only) and the ability to disable the charger.

An LED on the board indicates the status of the charging cycle.
