PW_max for the high- side FET depends also on the external bootstrap capacitance value. If the CBOOT voltage fal s below power on reset threshold voltage, the high-side GaN FET is switched OFF. The high-side circuit can be biased from an external 5 V floating voltage supply to al ow infinite turn on of the high-side FET.
