  • Publication number: 20250063827
    Abstract: An integrated circuit includes first to second transistors and a resistive device. The first transistor is coupled between a pad and a first voltage terminal that provides a first supply voltage. The second transistor is coupled in parallel with the first transistor. A breakdown voltage of the first transistor is different from a trigger voltage of the second transistor. The resistive device is coupled between the pad and a second voltage terminal that provides a second supply voltage higher than the first supply voltage, and operates with the second supply voltage in an electrostatic discharge (ESD) event when the first and second transistors discharge a ESD current between the pad and the first voltage terminal.
