FIELD: electricity.SUBSTANCE: in an integrated driver, comprising a preliminary cascade, the first output of which is connected with a base of an output transistor of the lower arm of a double-stroke output cascade, the second output of the preliminary cascade is connected to the output of the first source of current and with the base of the first transistor of n-p-n type, the emitter of which is connected to the output of the second source of current and with the base if the second transistor of n-p-n type, collectors of the first and second transistors are connected with a positive bus of a supply source, the emitter of the second transistor is connected with the appropriate output of the output transistor and with the output bus of the pulse shaper, the first source of current is made on a lateral transistor of p-n-p type, at the same time the collector of the lateral transistor is an output of the first source of current, and the output of the second source of current is an additional area of p-type, arranged inside the insulated n-pocket of the lateral transistor between its collector and the border of the insulating p-area of this n-pocket.EFFECT: reduced consumed power.1 cl, 3 dwg |
