  • Power supply ESD protection circuit
    Patent number: 5825601
    Abstract: An electrostatic discharge (ESD) protection circuit includes first and second supply terminals, a current source, a shunt transistor, an inverter and a voltage level shifting device. The shunt transistor is coupled between the first and second supply terminals and has a control terminal. The inverter includes an input coupled to the current source, an output coupled to the control terminal of the shunt transistor and pull-up and pull-down transistors coupled between the first and second supply terminals. The pull-up and pull-down transistors have control terminals which are coupled to the input. The voltage level shifting device is coupled between the input and the control terminal of one of the pull-up and pull-down transistors.
