level, the current sensing resistor should have an independent  
ground return to the star ground point. This trace should be  
as short as possible. For low value sense resistors, the IR  
drops in the PCB can be significant, and should be taken into  
account.  
Ground. A star ground should be located as close to the  
A3950 as possible. The copper ground plane directly under  
the exposed thermal pad makes a good location for the star  
ground point. The exposed pad can be connected to ground  
for this purpose.  
SENSE Pin. A low value resistor can be placed between  
the SENSE pin and ground for current sensing purposes. To  
When selecting a value for the sense resistor be sure not to  
minimize ground-trace IR drops in sensing the output current exceed the maximum voltage on the SENSE pin of ±500 mV.
