What Is a Gate Driver Circuit?
A gate driver circuit is specifically designed to operate power transistors, such as high-side or low-side power MOSFETs or IGBTs, efficiently.
Its core role is to process control signals and deliver the necessary current or voltage to the transistor’s gate, facilitating precise control over its switching functionality. This capability is essential for high-efficiency applications like power conversion and motor control, where rapid and reliable transistor switching is paramount.
Beyond its primary function, gate driver circuits incorporate protective features against overvoltage and overcurrent, enhancing their reliability. The performance of these circuits is critical in scenarios demanding fast and accurate switching for dependable power management.
