Classification: CPC H | IPC H

Claim 19:
20. A driver product for controlling a high-power drive device, the driver product comprising:
a first integrated circuit die and a second integrated circuit die implementing low-voltage control and isolation;
a third integrated circuit die including a variable strength driver circuit configured to provide a current to an output node of the third integrated circuit die, the current having a strength based on a received control signal and a predetermined profile of a multi-phase turn-on process for the high-power drive device coupled to the output node, a first indication of a sensed voltage level on the output node during a first phase of the multi-phase turn-on process, and a second indication of a time elapsed from a start of the first phase;
a fourth integrated circuit die including a second output node, a second variable strength driver circuit, and a second indicator circuit, the output node being coupled to the high-power drive device and the second output node being coupled to the high-power drive device or a second high-power drive device;
a first package housing the first integrated circuit die and the second integrated circuit die, the first package including standard power-dissipation features;
a second package housing the third integrated circuit die; and
a third package housing the fourth integrated circuit die, the second package and the third package each including enhanced power-dissipation features.
