Abstract:
An electrostatic discharge protection circuit includes a power clamp device, a timing circuit including a first resistor, a first capacitor that is connected with the first resistor at a first node, and a second capacitor that is connected to a second node, a logic gate including a first input connected with the first node, a second input connected with the second node, and an output connected with the power clamp device, and a decoder device connected with a first address pin and a second address pin. The first address pin and the second address pin are used to detect the power clamp device switching on at time of power on and draining current.
