Description

The Si85xx products are unidirectional ac current sensors available in full-  
scale ranges of 5, 10, and 20 A. Si85xx products are ideal upgrades for  
older current-sensing technologies offering size, performance and cost  
advantages over current transformers, Hall effect devices, DCR circuits  
and other approaches. The Si85xx are extremely low loss, adding less  
than 1.3 mΩ of series resistance and less than 2 nH series inductance in  
the sensing path at 25 ºC. Current-sensing terminals are isolated from the  
other package pins to a maximum voltage of 1,000 VDC.
