MAX1773 Evaluation Kit  
General Description  
Features  
ꢀ +4.75V to +28V AC-Adapter Input Range  
ꢀ Up to 5A Steering Capability  
The MAX1773 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 buck step-down battery charger, and an AC-  
adapter power source. The circuit uses a MAX1773 IC  
in a 20-pin TSSOP package and is configured for an  
AC-adapter input range of +4.75VDC to +28VDC.  
ꢀ P-Channel MOSFET Steering Switches  
ꢀ Adjustable Battery Minimum Voltage Level  
ꢀ SMBus Multiplexer  
The EV kit uses seven 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 +13V.  
ꢀ AC-Present and Battery-Status LEDs  
ꢀ Interfaces to MAX1772EVKIT Battery Charger  
ꢀ Surface-Mount Components  
ꢀ Fully Assembled and Tested  
The EV kit features an SMBus™ signal multiplexer that  
routes SMBus signals for the smart battery packs. LEDs  
are provided to indicate the status of the AC adapter  
and battery packs. The MAX1773 EV kit also demon-  
strates low-current usage with several options to  
reduce current usage.
