![]() Why Use a Gate Driver IC?Īs was mentioned above, a gate driver IC provides high current to a high-power transistor, such as an IGBT or a MOSFET, in order to fully drive it into the conduction state. Here’s how these components work and how to go about choosing a gate driver IC. These components are an integral part of power systems as they provide the required switching power while also protecting other critical components. High frequency applications may include an optimized gate driver circuit inside a transceiver or other RF component to provide the required power for switching a transistor amplifier, including in RF power amplifiers. Not all applications will need a gate driver IC. This power can be provided by a gate driver IC, which is specialized for providing a buffer between a controller and a power transistor. Larger transistors, both physically larger and in terms of their current output, require more power for switching. Any transistor requires some current to switch between ON and OFF states, thereby allowing current to flow across the device. These days, transistors come in all shapes and sizes, whether they are integrated into a CPU or available as discrete components.
