The MAX1538 evaluation kit (EV kit) is a fully assembled
and tested surface-mount circuit board that routes
charge and discharge currents between two battery
packs, a battery charger, and an AC-adapter power
source. The circuit uses a MAX1538 IC in a 28-pin thin
QFN package and is configured for a 4.75VDC to
28VDC AC-adapter input range.
The EV kit uses eight P-channel MOSFETs to steer current
between the power sources and the load. The battery
minimum voltage level sets the threshold for battery
undervoltage conditions and can be adjusted from
4.65V to 13.0V.
