Abstract
A switch controller coupled to control a transistor. The switch controller comprising an interface coupled to receive a command signal in response to an event sensed in a control system. The command signal is representative of a first command to control the transistor with a first drive strength or a second command to control the transistor with a second drive strength. The switch controller is coupled to adjust a fall time or a rise time, or to adjust both the fall time and the rise time, of a voltage across the transistor in response to the command signal. The fall time or the rise time, or both the fall time and the rise time in response to the second command is shorter than the fall time or the rise time, or both the fall time and the rise time in response to the first command.
Claims25
A switch controller coupled to control the turn on and turn off of a transistor, the switch controller comprising:
- an interface coupled to receive a command signal in response to an event sensed in a control system, wherein the command signal is representative of a first command to control the transistor with a first drive strength or a second command to control the transistor with a second drive strength,
- wherein the switch controller is coupled to adjust a fall time or a rise time, or to adjust both the fall time and the rise time, of a voltage across the transistor in response to the command signal, wherein the fall time or the rise time, or both the fall time and the rise time in response to the second command is shorter than the fall time or the rise time, or both the fall time and the rise time in response to the first command.
A switch controller coupled to control the turn on and turn off of a transistor, the switch controller comprising:
- an interface coupled to receive a command signal in response to an event sensed in a control system, wherein the command signal is representative of a first command to control the transistor with a first drive strength or a second command to control the transistor with a second drive strength,
- wherein the switch controller is coupled to adjust a gate current of the transistor in response to the command signal, wherein a magnitude of the gate current in response to the first command is smaller than the magnitude of the gate current in response to the second command.
