1. A circuit for detecting an under-voltage condition at a voltage input of a power supply, comprising:

  • a current mirror coupled to receive a current representing the voltage input of the power supply; and

    a reference current source to generate a reference current coupled to be received by the current mirror to generate an under-voltage signal when the reference current exceeds the current representing the voltage input of the power supply, the power supply being disabled when the under-voltage signal is generated.
