Ensure that SW1 is in the down position (charge
mode OFF).
Ensure that SW2 is in the down position (relearn
mode OFF).
Ensure that SW3 is in the down position (battery A
selected).
Set the DC power supply (used to emulate the bat-
tery charger) to 16.8V.
Set the DC power supply (used to emulate the AC
adapter) to 20V.
Ensure that all DC power supplies are turned off.
Connect the first battery to the BATA and GND
pads.
Connect the second battery to the BATB and GND
pads.

The MAX1538 EV kit circuit routes charge and dis-
charge currents between two battery packs, a battery
charger, and an AC adapter or DC power source. The
circuit uses a MAX1538 in a 28-pin thin QFN package
to control eight steering P-channel MOSFET switches.
