ABSTRACT:
A power control circuit achieves a relatively smooth turn-on conduction transition characteristic and a relatively low power consumption. A controlled transition circuit conducts current to a load when in a fully conductive state. The transition circuit transitions from a non-conductive state to the fully conductive state over a predetermined amount of time to limit the di/dt and the interference signals generated by the di/dt. A low forward voltage conduction circuit also conducts current to the load in a conductive state and diverts current to the transition circuit when in a non-conductive state. The conduction circuit creates a second predetermined voltage across the terminals when in the conductive state which is substantially less than the first predetermined voltage to reduce the power consumption.
