Abstract
A system and component for generating a drive signal suitable to operate a fuel injector. The drive signal includes one or more injector pulses. Each injector pulse is characterized by a desired pulse profile. The system includes an injector driver and a controller. The injector driver is operable to apply a supply voltage to the fuel injector. The controller is configured to store a plurality of state definitions that determine an operation state of the injector driver when a selected definition of the plurality of state definitions is communicated to the injector driver. The controller is further configured to receive a sequence of state values that determine an order that the state definitions are communicated to the injector driver to generate piecewise an injector pulse exhibiting the pulse profile, and thereby generate the drive signal.
