Abstract
A current driver system and method for generating one or more independent current signals for controlling or driving an external device. In one embodiment the system includes a programmable controller having both serial and parallel interfaces, and controls six independent current driver channels. Each current driver channel may form a dual stage channel that generates two different level current signals. Each current driver channel may include an overcurrent monitoring circuit as well as a loop back subsystem, where the loop back subsystem generates a signal that the programmable controller, and thus an external device in communication with the controller, can use to verify that proper communication is occurring between the controller and the current driver channel. The controller also synchronizes the turn on and turn off points for each current signal to a master system clock.
