Integrated circuit having electrostatic discharge protection
Abstract:
Apparatus are provided for integrated circuits that include circuitry to provide protection from electrostatic discharge. An exemplary integrated circuit includes an input/output terminal, a first transistor coupled to the input/output terminal, a second transistor coupled to a control terminal of the first transistor and a reference voltage node, and detection circuitry coupled to a control terminal of the second transistor. The detection circuitry is configured to turn on the second transistor in response to a discharge event to protect the first transistor.
