发明名称 Low voltage protection
摘要 A protection circuit for protecting components from an electrostatic discharge at a node in an integrated circuit having a first set of electronic components of a first voltage sensitivity, the protection circuit comprising: detection circuitry arranged to detect an electrostatic discharge at the node; a first switching device connected between the first set of components and the node; and a second switching device connected between the node and ground; wherein, when an electrostatic discharge is detected at the node, the first switching device is configured to isolate the first set of components from the node and the second switching device is configured to provide a current path from said node to ground.
