1. A method for controlling a high-power drive device, the method comprising:
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;
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; and
providing the current having a second predetermined current level to the output node during the second phase.
