Design of Innovative automotive electronic circuit protection
Automotive electronics is a hot development area recently, the booming Chinese auto market has brought new opportunities for the local automotive electronics industry. More and more companies have increased investment in automotive electronics products, including ECU, ABS, DVD, GPS, HVAC, CANBUS and so on, a large number of automotive electronics manufacturers design localization blossoming liter , which also create a new way for manufacturers of electronic components in the circuit protection design.
In the development of automotive electronics, almost every electrical device requires a fuse, commonly referred to as cable protection. The main role of the fuse is to limit the current increase, when there is an accident (such as a power short-circuit faults caused by accident), high current generated at this time you need to cut off the main power fuse immediately, to avoid further danger.

The traditional protection architectures for multi-car pole fuse cable and hierarchical, but most times an electronic device fails, only the faulty unit fuse cut off, without affecting the level circuit .

But in the process of car modification, such as adding a high-power external sound, it takes power from the battery, if the fuse used improperly, fuse will not break when it need to,then these glitches will affect the reliability of the vehicle system because of it, causing the fuse malfunction, therefore, good design and choice of fuse is especially important.
So,the circuit protection of car is necessary, especially nowadays that the car body has a lot of intelligent electronic devices, turns the previously purely mechanical car into the soul of "running robot." For electronic products, safety is paramount, car circuit fuse has thus become integrated and miniaturized.
