Abstract

A hot swap protection circuit system comprises multiple integrated circuits and a mainframe module. Each integrated circuit comprises a protection module, an on-off module, an on-off control module and a control interface module, wherein the control interface module and the mainframe module are mutually connected through a bus. The input end of each on-off module is connected with a load power source outside the corresponding integrated circuit, and the output end of each on-off module is connected with a load outside the corresponding integrated circuit. The protection modules are used for performing real-time detection on the on-off modules. If the detection result exceeds a standard value, an action command requesting protection is transmitted to the control interface modules. The control interface modules are used for transmitting a protection action command to the on-off control modules and transmitting fault information to the mainframe modules. The on-off control modules are used for receiving the protection action command to the control interface modules to control on-off of the on-off modules. The mainframe modules are used for storing addresses of the integrated circuits where faults happen.

Description

technical field [0001] The present application relates to a method for electrical protection circuit, in particular to a method for distributed hot swap protection circuit using integrated circuit IC Background technique [0002] The Hot Swap circuit design is widely used, and it is used as a protection measure for the components and chips of the hot-swappable equipment. When the electrical parameters of the load exceed its working standard, Hot Swap can disconnect the power supply, which has achieved the purpose of protecting electronic equipment. [0003] The current Hot Swap circuit uses discrete components to stack to achieve specific functions. The circuit is relatively complex, with a large number of design parameters, and due to the large error of the discrete components themselves, the distribution of electrical characteristics is also poor. Moreover, Due to the large number of components, the chances of sensitive signals being disturbed during PCB wiring are greatl...
