Abrégé
(EN)
An integrated circuit to drive fluid actuators is disclosed. The integrated circuit includes delay circuits coupled in series and to a fire input to receive a fire signal in succession. Each delay circuit receives the fire signal and, after a delay, provides the fire signal via an output to a corresponding fluid actuator. A programmable frequency generator is coupled to each of the of delay circuits. The programmable frequency generator provides a clock signal having an adjustable frequency to control the delay.

L'invention concerne un circuit intégré pour entraîner des actionneurs de fluide. Le circuit intégré comprend des circuits de retard couplés en série et à une entrée de déclenchement pour recevoir successivement un signal de déclenchement. Chaque circuit de retard reçoit le signal de déclenchement et, après un retard, fournit le signal de déclenchement par l'intermédiaire d'une sortie à un actionneur de fluide correspondant. Un générateur de fréquence programmable est couplé à chacun des circuits de retard. Le générateur de fréquence programmable fournit un signal d'horloge ayant une fréquence réglable pour commander le retard.
