Abstract
An integrated circuit with protection against transient electrical stress events includes a trigger circuit having a first detection circuit coupled to a first supply voltage, a second detection circuit coupled to a second supply voltage, and a rail clamp device. During a first type of electrical stress event, the rail clamp device is activated in response to a first output signal provided by the first detection circuit. During a second type of electrical stress event, the rail clamp device is activated in response to a second output signal provided by the second detection circuit.
