What is the approximate current drawn by Vgg? Does the Vgg driver need to be able to both source and sink current?
Thanks for the additional information.
Total current for Vgg pins typical vary between -2 to 30 mA, depending on temperature, input power and frequency.
Sink and source capability for the driver is needed, a shunt resistor on Vgg line, in kOhms range can help with that.
