The design should specify which type of input-to-out configuration should be used. If turning on the power MOSFET or IGBT when the input signal is in high state is preferred, then a device capable of the noninverting configuration must be selected. If turning off the power MOSFET or IGBT when the input signal is in high state is preferred, then a device capable of the inverting configuration must be chosen. Based on this noninverting requirement of this application, the proper device out of the UCC27322 or UCC37322 should be selected.
