  • Method and system for reducing transient event effects within an electrostatic discharge power clamp
    Patent number: 7639462
    Abstract: A method and system for reducing transient event effects, such as radiation effects, in an electrostatic discharge (ESD) power clamp is provided. The ESD power clamp includes triggering circuitry to determine the on-time of the power clamp during an ESD event, and drive circuits driving pull down devices to carry the ESD current. Two separate driver circuits are used to control the pull down circuits separately to guard against a single event effect (SEE). The ESD power clamp operates when both drive circuits are operated simultaneously to shunt the ESD to ground.
