Abstract
A method for driving a high-power drive device includes providing a signal having a first predetermined signal level to an output node during a first phase of a multi-phase transition process. The method includes generating a first indication of a first parameter associated with the signal provided to the output node. The method includes generating a second indication of a second parameter associated with the signal provided to the output node. The method includes providing the signal having a second predetermined signal level to the output node during a second phase of the multi-phase transition process. The method includes transitioning from the first phase to the second phase based on the first indication and the second indication. A multi-die, distributed package technique addresses power dissipation requirements for a driver product based on size and associated power dissipation needs of the high-power drive device in a target application.
