Abstract
A device for controlling a current controlled switching element includes an output node, a current driver circuit, and detection circuitry. The output node is configured to electrically couple to a control node of the current controlled switching element. The current controlled switching element is configured to change from operating in an off-state to operating in an on-state when a charge supplied to the control node causes a voltage at the control node to be greater than an activation threshold. The current driver circuit configured to output an activation current to the output node in response to a switching signal indicating to change from operating the current controlled switching element from the off-state to the on-state. The detection circuitry is configured to detect, based on the voltage at the control node, when a switching event has occurred while the current driver circuit outputs the activation current.
