The MAX1612 evaluation kit (EV kit) is a complete
bridge-battery management circuit. A small 2.4V,
50mAh NiCd battery, similar to the type commonly used
in bridge circuits of notebook computers, is mounted
on the board. When the main power source is discon-
nected, the MAX1612 boosts the 2-cell bridge battery
voltage to 6V to power the load. The MAX1612 also
controls the battery’s trickle charge cycle.
The MAX1612 evaluation board can also be used to
evaluate the MAX1613. Simply order a free sample of
the MAX1613EEE and replace the MAX1612 with the
MAX1613.

MAX1612 Evaluation Kit
The MAX1612 EV kit is shipped with the on-board bat-
tery disconnected. The battery must be charged before
use. Follow these steps to charge the battery and verify
board operation. Do not turn on the power supply
until all connections are completed.
1) Install a shunt across all jumpers to set the board

for operation without external signals. Note: Be sure
to reinstall the shunt across J2; prior to shipment,
this shunt was removed to disconnect the battery.
