Problems solved by technology
However, on the PCB circuit board, the fuse is soldered on the board by surface mount, and its package volume is relatively large. During the debugging process of the circuit board, replacing the blown fuse requires manual soldering, and the operation of removing the fuse and re-soldering is time-consuming. laborious
Moreover, during the debugging process, with the replacement of back-end devices or the adjustment of circuit power consumption, the rated current and breaking current requirements of the fuse will also change.
[0004] There is no effective solution to the problem of cumbersome replacement of fuses on PCB circuit boards and variable rated currents in the prior art.

The invention discloses a configuration method and a configuration device for a fuse chip. The configuration method comprises the steps of: writing configuration information into a state register according to a rated current by means of a controller; reading the configuration information from the state register by means of a decoder, and translating the configuration information into a level control signal; using the level control signal to and only to conduct one of a plurality of field-effect transistors; and accessing a fuse corresponding to the conducted field-effect transistor into a loop. The configuration method and the configuration device can package different fuses or fuses of different types into the chip for configuration, facilitate the circuit board to use the integrated fuses according to needs, and save the manpower for replacing the fuses.
Description
technical field [0001] The present invention relates to the field of communications, and more specifically, to a method and device for configuring a fuse chip. Background technique [0002] As a common short-circuit protection component, FUSE (fuse) is widely used in various PCB circuit boards, especially for power supply terminals of host fans and other components that support hot swapping. Under normal circumstances, the fuse acts as a connection in the circuit; when a short circuit occurs in the circuit, the current continues to increase until it reaches the breaking current threshold of the fuse. At this time, the fuse cuts off the current by fusing itself, thereby preventing other components in the circuit from being burned. Fuses are usually overcurrent and thermally blown, and they are non-recoverable, that is, once the fuse is blown, it needs to be replaced with a new fuse circuit to continue to work. [0003] The material of the fuse is usually metal or specific ce...
