MOSFET gate source protection

July 27, 2024

MOSFET itself has many advantages, but at the same time MOSFET has a more sensitive short-term overload capacity, especially in high-frequency application scenarios, so in the use of power MOSFETs must be developed for its effective protection circuit to enhance the stability of the device.

To put it bluntly overcurrent protection, is in the output of short-circuit faults or overload on the power supply or load maintenance, at this stage of the power supply overcurrent protection there are a variety of ways, such as constant-current, constant output power type, etc., but the development of such an overcurrent protection circuit can not be separated from the MOSFET, a high-quality MOSFETs can improve the role of power supply overcurrent protection.
