On-Board Status LEDs  
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 cur-  
rent between the power sources and the load. The bat-  
tery minimum voltage level sets the threshold for battery  
undervoltage conditions and can be adjusted from  
4.65V to 13.0V.
