Abstract
A driver circuit configured to control an operation of a relay includes: a voltage output electrically connected with the relay; a first voltage input selectively electrically connected to the voltage output; a buck boost converter including an input and a first output; and a system basis chip including an output terminal connected to the input of the buck boost converter and configured to provide a voltage. The first output of the buck boost converter is electrically connected to the first voltage input.
Claims15
A driver circuit configured to control an operation of a relay, the driver circuit comprising:
- a voltage output electrically connected with the relay;
- a first voltage input selectively electrically connected to the voltage output;
- a buck boost converter comprising an input and a first output, the first output being electrically connected to the first voltage input;
- and
- a system basis chip comprising an output terminal connected to the input of the buck boost converter and configured to provide a voltage.
A method of operating a relay comprising a driver circuit, the driver circuit comprising a voltage output electrically connected with a relay, a first voltage input selectively electrically connected to the voltage output, a buck boost converter comprising an input and a first output electrically connected to the first voltage input, and a system basis chip comprising an output terminal coupled to the input of the buck boost converter, the method comprising:
- closing a first switch arranged along an electrically conductive path between the second voltage input and the voltage output for a period of time to switch the relay into a closed state;
- closing a second switch arranged along the electrically conductive path between the first voltage input and the voltage output of the driver circuit after the period of time;
- and
- opening the first switch after the second switch is closed while maintaining the second switch in the closed state.
