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.
