Double-trigger driving circuit of intelligent fuse

The utility model discloses a double-trigger drive circuit of an intelligent fuse. The circuit comprises an internal trigger circuit, an external trigger circuit and a load circuit. The external trigger circuit and the internal trigger circuit are electrically connected with the load circuit and are used for safety protection when the load circuit is short-circuited; and the external trigger circuit is electrically connected with the internal trigger circuit to form double-circuit trigger. Safety protection of the power supply circuit is formed through the inner and outer double trigger circuits. 本实用新型公开了一种智能熔断器的双触发驱动电路，电路包括：内部触发电路、外部触发电路和负载电路；外部触发电路和内部触发电路均于负载电路电性连接，用于在负载电路出现短路情况时的安全保护；外部触发电路与内部触发电路之间也电性连接，形成双路触发。本实用新型通过内外双触发电路形成了对供电电路的安全保护。
