Gate driver circuit for current controlled switching element

A method comprising:

• determining a switching signal indicates to change from operating a current controlled switching element from an off-state to an on-state, the current controlled switching element configured to change from operating in the off-state to operating in the on-state when a charge supplied to a control node of the current controlled switching element causes a voltage at the control node to be greater than an activation threshold;
• in response to the switching signal indicating to change from operating the current controlled switching element from the off-state to the on-state, outputting an activation current to an output node configured to electrically couple to the control node, the activation current being configured to supply the charge to the control node to cause the voltage at the control node to be greater than the activation threshold;
• detecting, based on the voltage at the control node, when a switching event has occurred while outputting the activation current;
• and
• outputting a hold current to the output node when detecting that the switching event has occurred.
