PoE-PD Interface Controller, IEEE 802.3bt
NCP1095
Description The NCP1095 is a member of the ON Semiconductor Power over
Ethernet Powered Device (PoE−PD) product family, and allows the device containing the NCP1095 based PD to become an IEEE 802.3af/at and −3bt compliant powered equipment.
It incorporates all the required functions for operation within a PoE system such as detection, classification and current limiting during the inrush phase. The NCP1095 supports high-power applications (up to 90 W PoE) through an external pass transistor. A power good pin guarantees proper disabling/enabling of the adjacent main DC/DC converter. The classification result pins allow for operation according to the assigned power Class (up to Class 8).
