    Abstract: An integrated circuit comprising a power supply node, a ground node and a gated domain coupled between the power node and the ground node. A Charged Device Model electrostatic discharge protection module is provided for shunting electrical energy of a CDM ESD event away from the gated domain. A gating switch makes an electrical connection in a connected state between the gated domain and at least one of the power node and the ground node. ESD gating control circuitry is coupled to the CDM ESD protection module and controls shunting of energy away from the gated domain by the CDM ESD protection module, thereby avoiding the energy flowing through the gated domain. The ESD gating control circuitry inhibits actuation of the CDM ESD protection module to prevent response to CDM ESD events when the gating domain is powered-up.
