8.2.2.1 Input-to-Output Logic

The design should specify which type of input-to-output configuration should be used. The UCC27523 device can provide dual inverting input to output with enable control. The UCC27525 device can provide one inverting and one non-inverting input to output control. If turning on the power MOSFET or IGBT when the input signal is in high state is preferred, then the non-inverting configuration must be selected. If turning off the power MOSFET or IGBT when the input signal is in high state is preferred, the inverting configuration must be chosen. UCC27526 has dual configuration channel. Each Channel of UCC27526 device can be configured in either an inverting or non-inverting input-to-output configuration using the INx– or INx+ pins respectively like in Figure 8-2 and Figure 8-3. To configure the channel for use in inverting mode, tie the INx+ pin to VDD and apply the input signal to the INx– pin. For the non-inverting configuration, tie the INx– pin to GND and apply the input signal to the INx+ pin.
