Abstract

A system (10) and component (42) for generating a drive signal (20) suitable to operate a fuel injector (12). The drive signal (20) includes one or more injector pulses. Each injector pulse (21) is characterized by a desired pulse profile. The system (10) includes an injector driver (22) and a controller (25). The injector driver (22) is operable to apply a supply voltage to the fuel injector (12). The controller (25) is configured to store a plurality of state definitions (30) that determine an operation state of the injector driver (22) when a selected definition of the plurality of state definitions (30) is communicated to the injector driver (22). The controller (25) is further configured to receive a sequence of state values (34) that determine an order that the state definitions (30) are communicated to the injector driver (22) to generate piecewise an injector pulse (21) exhibiting the pulse profile, and thereby generate the drive signal (20).
