An integrated circuit includes a substrate, a GaN FET power switch disposed on the substrate, and a totally-GaN-based driver disposed on the substrate and coupled to the GaN FET power switch. The totally-GaN-based driver has an input terminal for receiving a supply voltage and includes an under-voltage detector having an output terminal. The under-voltage detector outputs a UVLO signal when the supply voltage is below a low-to-high threshold value, and does not output the UVLO signal when the supply voltage is above the low-to-high threshold value. The totally-GaN-based driver includes a pulse stretcher having an input terminal coupled to the output terminal of the under-voltage detector, and an output terminal for outputting a stretched_UVLO signal for a predetermined amount of time after the supply voltage first rises above the low-to-high threshold value.
