  • One wire parasite power switch control circuit
    Patent number: 9660638
    Abstract: A power switch control circuit is provided for power management in one-wire application. The circuit comprises a controllable switch coupled between an input node and an internal power node. A comparator is utilized for power loss sensing to close the switch when necessary to minimize the power loss while the input is low or floating. A watchdog circuit is incorporated within the control circuit to pull down the input node periodically to detect small leakage current when the input node is floating.

  • Active parasite power circuit
    Patent number: 8278782
    Abstract: A circuit is provided that includes a parasitic power circuit that powers a parasitic circuit. The parasitic power circuit derives a supply voltage from an external AC or other signal suitable for use as a communications signal. A PMOS transistor or transistors is utilized to enable a supply voltage capacitor to charge substantially to the same voltage as the channel voltage of the communications signal.
