8.3.5 UVLO Protection

The LMG365xR035 supports a wide range of VDD voltages. However, when the VDD voltage is below VDD UVLO threshold, the GaN device stops switching and is held off. The VDD UVLO voltage hysteresis prevents on-off chatter near the UVLO voltage trip point. The FLT/RDRV pin is pulled low as an indication of UVLO.
