Beschreibung
Zusammenfassung:	The invention discloses an overcurrent protection circuit and device, and belongs to the technical field of protectors, and the overcurrent protection circuit comprises an output control module which is connected with an input terminal and an output terminal, and is used for controlling the connection and disconnection between the input terminal and the output terminal according to a received working voltage; the current sampling module is connected with the output control module and is used for collecting the current of the output control module to obtain a sampling signal; and the overcurrent adjusting module is respectively connected with the current sampling module and the output control module and is used for controlling whether the working voltage is input into the output control module or not according to a comparison result of the adjustable reference voltage signal and the sampling signal so as to realize on-off control between the input terminal and the output terminal. The problem that an overcurre
