  • TEMPERATURE COMPENSATION FOR A CURRENT SENSE CIRCUIT
    Publication number: 20250044343
    Abstract: An integrated circuit includes a current sense circuit having an input, an output, and a correction current input terminal between the input and output. A first transistor has a first control input and a first terminal. The first terminal is coupled to the input of the current sense circuit. A second transistor has a second control input and a second terminal. The second control input is coupled to the first control input, and the second terminal is coupled to the correction current input terminal.

  • Gate driver with feed forward control of gate current
    Patent number: 12021517
    Abstract: A gate driver includes a gate current circuit and a driver logic circuit. The gate current circuit has a gate current circuit output and includes first and second current sources coupled to the gate current circuit output. The driver logic circuit has a capacitor and is configured to: charge and discharge the capacitor to generate a detect voltage across the capacitor; cause the first current from the first current source to flow to the gate current circuit output in response to a voltage on the gate current circuit output being below the detect voltage; and cause the second current from the second current source to flow to the gate current circuit output in response to the voltage on the gate current circuit output being above the detect voltage.
