MAX1507/MAX1508 Evaluation Kit
General Description
Features
The MAX1507/MAX1508 evaluation kit (EV kit) is a com-
plete, 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 charg-
ing cycle.

1) MAX1507: Verify that a shunt is installed on JU2
(TEMP) to set the charger to a +95 C regulated maxi-
mum die temperature. MAX1508: Remove the shunt
from JU2 and connect a 100k resistor from the
TEMP pad of the EV kit to the logic I/O voltage. The
ACOK logic signal is present at the TEMP test point.

3) Observe correct Li+ cell polarity. Connect a single-
cell Li+ battery across the BATT+ and BATT- pads of
the EV kit.
