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 m
Ω
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.
