Abstract
According to various embodiments, a circuit arrangement may be provided, comprising a driver circuit configured to deliver a switching signal to a power switch such that the power switch controls a load current, a gate-back regulation circuit selectively connected to the driver circuit and the load current, and a diagnostic circuit configured to provide an enabling signal, which allows the gate-back regulation circuit to become active; and wherein the enabling signal is dependent at least in part on a condition independent of the load current.
Claims18
A circuit arrangement comprising:
- a driver circuit configured to deliver a switching signal to a power switch such that the power switch controls a load current;
- a gate-back regulation circuit connected to the load current;
- and
- a diagnostic circuit configured to provide an enabling signal, which allows the gate-back regulation circuit to become active;
- wherein the diagnostic circuit is configured to receive information from the power switch;
- wherein the enabling signal is dependent at least in part on a condition independent of the load current.
