PRODUCTION DATA
A gate to source resistor, RGS, is recommended to pull down the gate to the source voltage when the gate driver output is unpowered and in an indeterminate state. This resistor also helps to mitigate the risk of dv/dt induced turn-on due to Miller current before the gate driver is able to turn on and actively pull low. This resistor is typically sized between 5.1 kΩ and 20 kΩ, depending on the Vth and ratio of CGD to CGS of the power device.
