Abstract
A protection circuit may include a fuse configured to couple in series with a load. The protection circuit may include a device coupled to the fuse and configured to couple in parallel with the load. The device may be configured to, in response to an increase in current above a threshold, operate in an active state to route at least a portion of the current through the device and to the fuse. In examples, the device includes a solid-state device, a mechanically-actuated device, and/or a pyro-actuated device.
Claims20
A protection circuit comprising:
- a fuse configured to couple in series with a load;
- and
- a device coupled to the fuse and configured to couple in parallel with the load, the device configured to, in response to an increase in current above a threshold, operate in an active state to route at least a portion of the current through the device and to the fuse, the device including at least one of a solid-state device, a mechanically-actuated device, or a pyro-actuated device.
A circuit comprising:
- a fuse configured to couple in series with a load;
- and
- a device coupled to the fuse and configured to couple in parallel with the load, the device configured to, based on an overcurrent event, switch the circuit to a load bypass state to cause at least a portion of an overcurrent to pass through the device and reach the fuse without flowing to the load.
