Abstract:
An apparatus includes a transistor coupled to a load through an output terminal of a load switch IC, a gate drive circuit connected to a gate of the transistor, wherein the gate drive circuit is configured such that in a short circuit event, a voltage on the gate of the transistor is gradually reduced, and wherein as a result of reducing the voltage on the gate of the transistor gradually, a negative voltage occurring at the output terminal of the load switch IC is minimized.
