Description
The AUIPS6121R is a fully protected four terminal high
side switch. It features current sensing, over-current, over-
temperature, ESD protection and drain to source active
clamp. Shutdown type of protection provides a good
reliability under short circuit condition. The Ifb pin provides
both an analog feedback during normal operation and a
digital flag when the part is in protection mode.
