Abstract
A passive leakage management circuit for a switch leakage current includes a switch being operable in a first operating mode, wherein the switch output supplies an output current having a first predetermined voltage. In a second operating mode, the switch output supplies a leakage current having a second voltage, a first current path, and a leakage current path.
Claims15
A passive leakage management circuit for a switch leakage current comprising:
- a switch having a switch input, and a switch output electrically coupled with an electrical load, and operable in a first and a second operating mode, wherein in the first operating mode the switch output supplies an output current provided to the input and having a first predetermined voltage, and in the second operating mode the switch output supplies a leakage current from the input and having a second voltage lower than the first voltage;
- a first current path comprising at least a first transistor, wherein the first transistor conducts current along the first current path based on the switch output;
- and
- a leakage current path comprising at least a second transistor, wherein the second transistor conducts current along the leakage current path based on the first transistor conducting current;
- wherein at least one of the first current path or leakage current path conducts current automatically based on the switch output, without an additional power source beyond the switch output, and independent of the state of the switch.
