Variable current drive for isolated gate drivers

A method for controlling a high-power drive device includes providing a current having a first predetermined current level to an output node during a first phase of a multi-phase turn-on process for the high-power drive device coupled to the output node. The method includes transitioning from the fi...

Zusammenfassung:	A method for controlling a high-power drive device includes providing a current having a first predetermined current level to an output node during a first phase of a multi-phase turn-on process for the high-power drive device coupled to the output node. The method includes transitioning from the first phase to a second phase of the multi-phase turn-on process based on a first indication of a sensed voltage level on the output node during the first phase and a second indication of a time elapsed from a start of the first phase during the first phase. The method includes providing the current having a second predetermined current level to the output node during the second phase.
