Patent ID: 7236043

Claim:
An electrical conduction control and sending device comprising: a control circuit coupled to an input of the electrical conduction control and sensing device; an electrically configurable conduction device coupled to the control circuit, the electrically configurable conduction device having a low conductivity and capable of having a high conductivity; a sense amplifier coupled to the electrically configurable conduction device, the sense amplifier capable of producing a sense current, detecting a magnitude of voltage produced by the sense current, and producing a blown signal at an output of the electrical conduction control and sensing device; and a coupling circuit coupled to the electrically configurable conduction device and the sense amplifier, the coupling circuit having means for electrically communicating the sense current produced by the sense amplifier to the electrically configurable conduction device when the coupling circuit is enabled and for electrically protecting the sense amplifier when the coupling circuit is disabled.
