Title:
APPARATUS FOR DISCONNECTING CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2023/174061
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are an apparatus for disconnecting a circuit. The apparatus for disconnecting a circuit comprises: an input interface, an output interface, a first capacitor, a control assembly and a field effect transistor, wherein a first interface of the input interface is connected to a positive electrode of an external circuit, and a second interface thereof is connected to a negative electrode of the external circuit; a first end of the first capacitor is connected to the first interface, and a second end thereof is connected to the second interface; the field effect transistor is arranged between the first capacitor and the first interface, or is arranged between the first capacitor and the second interface; and the control assembly is used for controlling the field effect transistor to disconnect the circuit when it is detected that the first interface and the second interface are short-circuited. In the embodiments of the present application, when short-circuit occurs, a circuit is disconnected by using a field effect transistor, thereby reducing the power consumption of an apparatus for disconnecting a circuit.
