Abstract
A system includes a latch circuit configured to monitor a switch and to operate an electronic latch based on a position of the switch. The system also includes a power supply circuit configured to provide a first voltage level to the latch circuit during normal operations and a second voltage level to the latch circuit during power loss. The power supply circuit includes a primary power circuit configured to provide the first voltage level to the latch circuit and a plurality of supercapacitors configured to be charged by the primary power circuit and provide the second voltage level to the latch circuit.
Claims20
A system comprising:
- a latch circuit configured to monitor a switch and to operate an electronic latch based on a position of the switch;
- and
- a power supply circuit configured to provide a first voltage level to the latch circuit during normal operations and a second voltage level to the latch circuit during power loss, wherein the power supply circuit comprises:
- a primary power circuit configured to provide the first voltage level to the latch circuit;
- and
- a plurality of supercapacitors configured to be charged by the primary power circuit and provide the second voltage level to the latch circuit.
A method comprising:
- providing, by a primary power circuit, a first voltage to a latch circuit;
- applying a first voltage level to an electronic latch coupled with the latch circuit in response to receiving an unlatch command;
- charging, by the primary power circuit, a bank of supercapacitors;
- and
- monitoring the first voltage level from the primary power circuit and in response to determining a loss of the first voltage level, applying a second voltage level from the bank of supercapacitors to the electronic latch.
