Patent number: 11674470Abstract: A system for controlling the operation of one or more fuel injectors includes a microcontroller, a pre-driver unit, and a power unit. The system is connectable to an electrically actuated fuel injector via at least two wires from the power unit, wherein the pre-driver unit is located between the microcontroller and the power stage, and wherein the microcontroller unit is adapted to send data to the pre-driver unit. The pre-driver unit is adapted to receive the data and control the power stage dependent on the data such that the power stage is adapted to output a corresponding signal along the wires to the fuel injector. The data includes both injector activation pulse data and other auxiliary data for the injectors.Type: GrantFiled: October 9, 2018Date of Patent: June 13, 2023Assignee: DELPHI AUTOMATIVE SYSTEMS LUXEMBOURG SAInventors: Felix Mandoux, John Mark Dikeman

Patent number: 11293808Abstract: 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.Type: GrantFiled: June 30, 2021Date of Patent: April 5, 2022Assignee: Delphi Technologies IP LimitedInventors: Soumyajit Routh, Kevin M.

Patent number: 10371082Abstract: 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.Type: GrantFiled: January 22, 2018Date of Patent: August 6, 2019Assignee: DELPHI TECHNOLOGIES IP LIMITEDInventors: John Mark Dikeman, Mark W.

Patent number: 10221800Abstract: 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.Type: GrantFiled: January 22, 2018Date of Patent: March 5, 2019Assignee: DELPHI TECHNOLOGIES IP LIMITEDInventors: Mark W.

Patent number: 6034561Abstract: A transient suppressor comprises a self-triggered silicon control rectifier (SCR) that forms a drive circuit for an NPN power transistor. The SCR and the NPN power transistor are combined, along with other elements, into an integrated circuit (IC) by a junction isolated BiCMOS process. The SCR self-triggers upon being subjected to an inductive flyback condition created by an inductive load and renders the NPN transistor conductive, thereby allowing the NPN power transistor, having a relatively large semiconductor region, to effectively snub the current created by the negative feedback condition. The transient suppressor may be used in either a high-side or low-side driver arrangement and the SCR/NPN power transistor combination may further be combined with load driving and other circuitry on a single integrated circuit.Type: GrantFiled: April 9, 1999Date of Patent: March 7, 2000Assignee: Delco Electronics CorporationInventors: John Mark Dikeman, Mark Wendell Gose

Patent number: 5796278Abstract: Circuitry for controlling load current, in accordance with the present invention, utilizes a load drive transistor configuration operable to provide a first load current path having a first fraction of load current flowing therethrough and a second load current path having a second smaller fraction of load current flowing therethrough. The circuit includes a sense resistor associated with the load drive transistor to detect various load current threshold values. In order to reduce debiasing effects of the sense resistor upon the second load current path of the load drive transistor, a compensation resistor is provided between drive inputs associated with each of the two current paths. The compensation resistor has a compensation voltage established thereacross which is operable to negate the debiasing effect of the sense resistor on the load driving device.Type: GrantFiled: April 26, 1996Date of Patent: August 18, 1998Assignee: Delco Electronics CorporaitonInventors: Douglas Bruce Osborn, Mark Wendell Gose, John Mark Dikeman
