PoE-PD Interface Controller, IEEE 802.3bt NCP1096 Description The NCP1096 is a member of the ON Semiconductor Power over Ethernet Powered Device (PoEPD) product family, and allows the www.onsemi.com device containing the NCP1096 based PD to become an IEEE 802.3af/at and 3bt compliant powered equipment. RELATED STANDARDS It incorporates all the required functions for operation within a PoE IEEE 802.3bt2018 system such as detection, classification and current limiting during the inrush phase. The NCP1096 supports high-power applications (up to 90 W PoE) through an internal pass transistor. A power good pin guarantees proper disabling/enabling of the adjacent main DC/DC 16 converter. The classification result pins allow for operation according to the assigned power Class (up to Class 8). 1 The NCP1096 also offers Autoclass support and indicates when a short Maintain Power Signature can be implemented. In addition an TSSOP16 EP CASE 948BV auxiliary supply detection pin allows NCP1096 to be used in applications where power can be supplied by either PoE or by a wall adapter.
