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

L'invention concerne un circuit intégré destiné à commander une pluralité d'actionneurs de fluide. Les circuits à retard analogique de circuit intégré sont couplés en série et à une entrée d'allumage pour recevoir successivement un signal d'allumage. Chaque circuit à retard analogique reçoit le signal d'allumage et, après un certain délai, fournit le signal d'allumage par l'intermédiaire d'une sortie à un actionneur de fluide correspondant. Un circuit de polarisation est couplé à chacun des circuits à retard analogique. Le circuit de polarisation fournit un signal de polarisation pour réguler le retard.
