The LMG2100R044's inputs pins are independently controlled with TTL input thresholds and can can support 3.3-V and 5-V logic levels regardless of the VCC voltage.

In order to allow flexibility to optimize deadtime according to design needs, the LMG2100R044 does not implement an overlap protection functionality. If both HI and LI are asserted, both the high-side and low-side GaN FETs are turned on. Careful consideration must be applied to the control inputs in order to avoid a shoot-through condition.
