With the continuous development of China's economy, cars have become an essential means of transportation for people's travel. With the increasing number of urban cars, the application of the fuse industry in the automotive field is also becoming more and more widespread. Currently, 40% of cars use various electronic devices. So where do we need to provide over temperature/over voltage/over current protection, and what devices should be used for correct protection? This issue requires us to have a deeper understanding.

The main applications of self restoring fuses in automotive circuit protection devices include small and medium-sized car motors, wiring harness junction boxes, automotive circuits, and automotive consumer electronics. Automotive electronic protection includes battery charging circuits, cigarette lighter interfaces, PCB wiring, and IEEE1394 networks; In car consumer electronics include in car audio, DVD, TV, etc.

self recovery fuses are used in automobiles to prevent dangerous situations such as circuit overcurrent/overheating caused by various faults, such as motor blockage in controlling doors, windows, skylights, and seats, short circuits caused by wire harness wear, secondary short circuits in transformer coils, reverse connections in battery boxes, and abuse of cigarette lighters. Overvoltage caused by car starting, braking, and battery box plugging can be protected by overvoltage devices. The self restoring fuse should be able to withstand various overvoltage impacts inside the vehicle.

Self Recovery Performance and Working Process of Self Recovery Fuses

Traditional fuses are installed in circuits. When an overcurrent occurs due to a fault or abnormality in the circuit, the fuse itself melts to cut off the current and protect the circuit. However, due to the fact that traditional fuses can only protect once and need to be replaced if burned out, some products still cannot resume operation after troubleshooting or abnormal overcurrent disappears. As a new type of overcurrent protection device, the self-recovery fuse has the function of automatic recovery, which can meet the performance requirements of similar applications.

The Application of Self Recovery Fuses in RS485 Interface

As is well known, the interface of intelligent instruments was originally RS232, which can achieve point-to-point communication, but this method cannot achieve networking function. The subsequent RS485 resolved this issue. So the current RS485 interface is quite popular among intelligent instruments. Today, the editor will explain the application of self recovery fuses in the RS485 interface.

Self Recovery Fuse on Mobile Power PCB Board

The mobile power supply consists of overcurrent protection devices, batteries, and control charging and discharging circuits. The previous charging and discharging circuits used ICs for overcurrent protection, which were complex, had high failure rates, and high costs. Some users returned or repaired the circuit, and the manufacturer was fined and claimed compensation, which caused great trouble for manufacturers and designers. The above problems must be solved in order to promote their application.
