The circuit is used in medical applications to provide the actuation to transfer the drug from the drug reservoir to the body with accuracy and reliability. This reference design is used to operate a piezoelectric micropump controlling the flow of fluid upon delivery. A micropump is a mini mechanical pumping device with a piezoelectric actuator and passive check valves. The design is mainly composed of the control board, high voltage driver board and the piezoelectric micropump. Read more
