Title:
INDUCED LOAD SWITCHING CONTROL CIRCUIT
Document Type and Number:
Japanese Patent JPS58184618
Kind Code:
A
Abstract:
A control circuit for the switching of inductive loads which is monolithically integratable and includes an output stage having push-pull transistors. The base of each transistor of the output stage is connected to a driver circuit and to an auxiliary transistor which is biased in saturation. Each auxiliary transistor is driven to conduction in phase opposition with respect to the final transistor to which it is connected. The auxiliary transistor accelerates the turn-off of the final transistor, withdrawing the base charge, while delaying the turn-on thereof and absorbing the current fed thereto for a period of time equal to that of its own turn-off transient; in this way, the simultaneous conduction of the transistors of the final stage during the switching thereof can be avoided.
