UPDATING CONTROL PARAMETERS OF A GATE DRIVER DURING OPERATION

Abstract: 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.
