Abstract:
Techniques are described to slow the turn off of a pass transistor coupled to an inductive load and being controlled by a hot swap or switch controller in the event of a fault on the load side. Active circuitry can control the gate of the pass transistor, e.g., field-effect transistor (FET), as the inductive load de-energizes and a feedback loop can servo the gate voltage of the pass transistor in order to ensure that its source does not go below a reference voltage.
