Abstract
A low-power-consumption protection circuit includes a load detection module, a secondary feedback control module, and a primary control module. The load detection module is coupled to a current detection unit. The secondary feedback control module is coupled to the load detection module and an isolation unit. The primary control module is coupled to the isolation unit and an isolation switch. When the load detection module detects that the current detection unit outputs a voltage level, the secondary feedback control module transmits a protection signal to the primary control module through the isolation unit.
