8.3.1 Control Inputs

The LMG5200's inputs pins are independently controlled with TTL input thresholds and can withstand voltages up to 12V regardless of the VDD voltage. This allows the inputs to be directly connected to the outputs of an analog PWM controller with up to 12V power supply, eliminating the need for a buffer stage.

In order to allow flexibility to optimize deadtime according to design needs, the LMG5200 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.
