The LMG2100R026 has an UVLO on both the VCC and HB (bootstrap) supplies. When the VCC voltage is below the threshold voltage of 3.8V, both the HI and LI inputs are ignored, to prevent the GaN FETs from being partially turned on. Also, if there is insufficient VCC voltage, the UVLO actively pulls the high- and low-side GaN FET gates low. When the HB to HS bootstrap voltage is below the UVLO threshold of 3.2V, only the high-side GaN FET gate is pulled low. Both UVLO threshold voltages have 200mV of hysteresis to avoid chattering.
