Abstract
An electrostatic discharge (ESD) protection control circuit for an output pad of an integrated circuit includes an output driver and a control switch. The output driver, coupled to the output pad, includes a first output transistor for outputting power or signals to the output pad. The control switch, for improving ESD protection on the output pad when closed, includes a first connection terminal, coupled to a gate terminal of the first output transistor; a second connection terminal, coupled to a ground terminal; and a control terminal, coupled to a first power supply terminal.
