Low voltage electrostatic discharge protection

A protection circuit for protecting components from an electrostatic discharge at a first node in an integrated circuit having a first set of electronic components, the first set of electronic components having a first voltage sensitivity, the first set of electronic components being supplied with a voltage supply by a second node, the protection circuit comprising:

• a first switching device connected between the first node and the second node;
• a second switching device connected between the first node and ground;
• a third switching device connected between the second node and ground;
• and
• detection circuitry arranged to detect an electrostatic discharge at the first node and in response to said detection, to control the switching devices such that:
• the first switching device is switched off to isolate the first set of electronic components from the first node, the second switching device provides a current path from the first node to ground, and the third switching device provides a current path between the second node and ground, bypassing the first set of components.
