Enable Function

An enable and disable function can be easily implemented in the UCC27611 device using the unused input pin. When IN+ is pulled down to GND, or IN– is pulled down to VDD, the output is disabled. Thus, IN+ pin can be used like an enable pin that is based on active high logic, while IN– can be used like an enable pin that is based on active low logic.
