Application of YFW Youfeng Micro MOS Tube in Automotive Emergency Start Power Supply

What is an emergency starting power supply for automobiles? It is a multifunctional portable power supply developed for driving, outdoor enthusiasts, and business people. As an extension product of mobile power banks, its characteristic function is to enable the car to start when it is unable to start normally due to power loss or other reasons. At the same time, it combines emergency power supply, outdoor lighting, mobile power supply, laptop power supply and other functions, making it one of the essential products for outdoor travel

In the field of automotive electronics, MOS transistors are widely used. Most of them are used as switching transistors, and MOS transistors are indispensable in power supplies and various types of power drives.

There are two options for emergency start-up power: batteries and supercapacitors. During use, due to long charging time, low power, short cycle life, there is room for improvement. The shortcomings of the battery itself are exposed, and the battery itself has strict requirements for the operating environment. The optimal operating temperature is between 20~30 ℃, long charging time, low discharge power, short cycle life, and there is room for improvement. So MOS transistors play an important role in emergency power supplies for automobiles.
