Abstract:
1. A drive circuit for a power device, comprising: a high side driver having a first power transistor adapted to couple to a first end of a drive coil, the high side driver having a first inductor tuned to a gate capacitance of the first power transistor to supply at least 80% of maximum current to the gate of the first power transistor as the gate capacitance of the first power transistor transitions through its Miller region; and a low side driver having a second power transistor adapted to couple to a second end of the drive coil, the low side driver having a second inductor tuned to a gate capacitance of the second power transistor to supply at least 80% of maximum current to the gate of the second power transistor as the gate capacitance of the second power transistor transitions through its Miller region.
