Smart Two Channel Highside Power Switch

Features

• Overload protection

• Current limitation

• Short-circuit protection

• Thermal shutdown

• Overvoltage protection

• Fast demagnetization of inductive loads

• Open drain diagnostic output

• Open load detection in OFF-state

• CMOS compatible input

• Loss of ground and loss of V
