Abstract:
An apparatus for determining a state of a programmable coupling device, comprising:a logic circuit having an input for receiving an internal power signal and an output terminal for providing a compensation signal having an output level with a first proportionality to the internal power signal; a voltage regulator having an input for receiving the internal power signal and an output terminal for providing a supply signal having a second proportionality to the internal power signal that is less than the first proportionality; and a continuity detecting circuit coupled to the programmable coupling device and having a supply terminal coupled to the output of the voltage regulator, a compensation terminal coupled to the output of the logic circuit, a control terminal for receiving an activation signal, and an output terminal, the continuity detecting circuit generating at the output terminal when it activated an indicator signal having a logic level indicative of the state of the programmable coupling device.
