Description
The AUIPS71411G is a fully protected four terminal high
side switch specifically designed for 24V battery
application. It features current sensing, over-current, over-
temperature, ESD protection and drain to source active
clamp. When the input voltage Vcc - Vin is higher than the
specified threshold, the output power Mosfet is turned on.
When the Vcc - Vin is lower than the specified Vil
threshold, the output Mosfet is turned off. The Ifb pin is
used for current sensing.
