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.
