摘要： Embodiments of this application provide an integrated circuit, a chip, and an electronic device, and relate to the field of microelectronic circuit technologies, to reduce an integrated circuit malfunction caused by electrostatic discharge. The integrated circuit includes a substrate and a transistor disposed on the substrate. A gate of the transistor is coupled to a first end of a switch component, and a second end of the switch component is coupled to a ground end. The switch component is configured to be in a turn-on state or a turn-off state under control of a control signal received by a control end. The switch component in the turn-on state transmits an electrostatic voltage of the gate of the transistor to the ground end. Alternatively, the switch component in the turn-off state disconnects the gate of the transistor from the ground end.
