  • Apparatus and methods for improved circuit protection from EOS conditions during both powered off and powered on states
    Publication number: 20070115600
    Abstract: Apparatus and methods for protecting an electronic application circuit from electrical over-stress (EOS) conditions both while the application circuit is powered on and while the application circuit is powered off. In one aspect apparatus is provided that integrates with the application circuit that utilizes an existing clamp circuit to guard against EOS conditions while the application circuit is powered off and while the application circuit is powered on. The apparatus may include a clamp circuit for EOS protection while the application circuit is powered on and may include a band-gap reference voltage source coupled to activate the clamp circuit when the application circuit is powered on.
