Abstract: An illustrative embodiment of a fuel injector control system includes a driver that is configured to supply electrical power to a fuel injector. A controller is configured to control the driver by implementing a predetermined sequence of a plurality of states for an injection cycle. The plurality of states each include parameters for supplying electrical power to the fuel injector. The controller selects one of the states to implement as a next one of the states in the sequence based on a characteristic of an activation signal and information indicative of the state corresponding to the characteristic of the activation signal.

Abstract: An illustrative embodiment of a fuel injector control system includes a driver that is configured to supply electrical power to a fuel injector. A controller is configured to control the driver according to a predetermined sequence of states for an injection cycle. The plurality of predefined states each include parameters for supplying electrical power to a fuel injector. Each of the states has a corresponding plurality of test parameters. At least one of the test parameters is a target parameter for the state. During each of the states, the controller determines whether at least one of the test parameters is met and determines how to control the driver for a subsequent portion of the injection cycle based on which of the test parameters is met.

Abstract: A method includes, responsive to an application of power to an IC, self-initializing the IC by asserting a reset signal for a reset period. Self-initializing the IC also includes, in response to an expiration of the reset period, deasserting the reset signal. Self-initializing the IC also includes, responsive to deasserting the reset signal, automatically obtaining first temperature data from at least one thermal sensing device associated with a die of the IC, and storing the first temperature data in a storage component of the IC.
