Fluid injection device preventing activation of a bipolar junction transistor (BJT) therein

摘要

Fluid injection devices comprise M sets of fluid injection units. Each fluid injection unit comprises N injectors separately connecting to a driver. A controller separately transmits a signal to the driver, thereby simultaneously driving a selected injector of each of the M sets of fluid injection units. A non-selected injector of each of the M sets of fluid injection units does not trigger bipolar junction transistors (BJTs).
