Patent number: 11962233Abstract: An isolated gate driver has a first portion in a first voltage domain and a second portion in a second voltage domain. The first and second portions are coupled by an isolation communication channel. The isolated gate driver transmits across the isolation communication channel a serial word containing first drive strength information and simultaneously transmits gate information with the serial word across the isolation communication channel. The gate information indicates a state of a gate signal for a transistor coupled to the second portion of the isolated gate driver. A demodulator circuit demodulates a signal containing the gate information and the drive strength information transmitted across the isolation communication channel in the serial word. A gate signal output circuit coupled to the demodulator circuit supplies the gate signal based on the gate information with a drive strength of the gate signal being based on the drive strength information.Type: GrantFiled: May 1, 2023Date of Patent: April 16, 2024Assignee: Skyworks Solutions, Inc.Inventors: Michael Robert May, Fernando Naim Lavalle Aviles, Carlos Jesus Briseno-Vidrios, Patrick Johannus De Bakker, Gabor Marek, Charles Guo Lin, Peter Onody, Tamas Marozsak, Andras V.
