1. MOSFET drive current depends on the specific application and design requirements. 2. The size of the drive current is mainly determined by the load characteristics of the MOSFET, the operating frequency, the amplitude of the input signal and the design of the drive circuit. In general, the drive current needs to be large enough to ensure that the MOSFETs can be switched on and off quickly, while also avoiding excessive current that leads to power consumption and heat issues. 3. In some common applications, such as power switches, motor drives, etc., usually require tens to hundreds of MA drive current.
In high-frequency applications, the drive current may be larger due to the need for faster switching speeds. Therefore, the size of the MOSFET drive current is determined according to the specific application needs, and the combined influence of multiple factors needs to be considered.
