Description
The AUIPS7141R is a fully protected four terminal high
side switch specifically designed for driving lamp. 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. The over-current shutdown is higher than inrush
current of the lamp.
