Patent number: 12155332Abstract: A gate driver includes a variable strength driver circuit that provides an output signal to drive a high power device. The gate driver receives an update request from a host controller during an operating mode in which switching operations occur and updates one or more operating parameters associated with driving the high power device. The operating parameters including turn-on parameters, turn-off parameters, and soft shutdown parameters. The variable strength driver circuit uses the turn-on parameters for turn-on phases for the output signal, uses the turn-off parameters for turn-off phases for the output signal, and uses the soft shutdown parameters for soft shutdown phases for the output signal. The update request adjusts current, voltage, and/or time for one or more phases of the turn-on, turn-off and/or soft shutdown parameters.Type: GrantFiled: March 31, 2021Date of Patent: November 26, 2024Assignee: Skyworks Solutions, Inc.Inventors: James E. Heckroth, Ion C. Tesu, John N. Wilson

Publication number: 20240204756Abstract: A method for controlling a high-power drive device includes providing a current having a first predetermined current level to an output node during a first phase of a multi-phase turn-on process for the high-power drive device coupled to the output node. The method includes transitioning from the first phase to a second phase of the multi-phase turn-on process based on a first indication of a sensed voltage level on the output node during the first phase and a second indication of a time elapsed from a start of the first phase during the first phase. The method includes providing the current having a second predetermined current level to the output node during the second phase.Type: ApplicationFiled: November 20, 2023Publication date: June 20, 2024Inventors: Ion C. Tesu, James E. Heckroth, Stefan N. Mastovich, John N. Wilson, Krishna Pentakota, Michael Ireland, Greg Ridsdale, Lyric Jackson

Publication number: 20240186988Abstract: A method for validating operation of a driver integrated circuit includes providing a signal using an output node. The signal is provided using multiple set points in response to a change in state of an input signal. Each set point corresponds to a different phase of a multi-phase transition of the signal. The method includes providing a timer value at an end of a phase of the multi-phase transition and determining whether the signal is in a target signal range of the phase based on the timer value at the end of the phase, a predetermined value defining the target signal range of the phase, and a predetermined time limit for the phase. A current through the output node may be provided using the multiple set points, and a voltage on the output node may have the multi-phase transition.Type: ApplicationFiled: September 29, 2023Publication date: June 6, 2024Inventors: James E. Heckroth, Ion C. Tesu

Publication number: 20220188262Abstract: Each device on a bus auto-enumerates at power up or reset to assign a unique address to the device based on the resistance value of an external resistor. A current source supplies a current to a terminal to which a resistor is coupled. Each device has a resistor attached with a different resistance value. Each device senses the voltage at the terminal and the voltage corresponds to the unique device address on the bus. Following enumeration, the devices on the bus are individually addressable using their unique address.Type: ApplicationFiled: December 9, 2021Publication date: June 16, 2022Inventors: James E. Heckroth, Patrick Johannus De Bakker, Ion Constantin Tesu, Phillip M. Matthews
