A control circuit for a solenoid driver for a dispenser having inherent pull-in and drop-out delays. The circuit includes a tachometer that generates pulses representative of the speed of a conveyor that conveys a substrate upon which the dispenser dispenses fluid. A sensor generates a trigger signal indicating that the substrate is at a preselected location. Delay counter circuitry enabled through the trigger signal, generates an enabling signal after receiving a preselected number of pulses. Duration counter circuitry enabled by the, enabling signal, generates an initial driving signal of a preselected signal duration. Compensator circuitry receives the initial driving signal and modifies …
