The interrupt is primarily used to detect classification and disconnection events, which are essential for managing the PSE controller in compliance with the PoE standard. Interrupt support is essential for the proper functioning of the TPS23881 controller. Without it, after a power-on (PWON), the controller will no longer perform detection and classification. This could lead to potential hazards, such as connecting a non-PoE device after a PoE device, which might result in magic smoke.
