onsemi NCP1095 PoE PD interface controller IEEE 802.3bt
The Power Over Ethernet (PoE) Powered Device (PD) Interface Controller NCP1095 contains all features needed to implement an IEEE.3bt, IEEE 802.3af, and/or IEEE 802.3at application
The Power Over Ethernet (PoE) Powered Device (PD) Interface Controller NCP1095 contains all features needed to implement an IEEE.3bt, IEEE 802.3af, and/or IEEE 802.3at application. This includes detection, classification, and current limiting. The NCP1095 supports high power applications up to 90W through an external pass transistor. A power good and auxiliary power supply detection pin guarantee a proper enabling or disabling of the DC/DC converter to comply with type I, II, III and IV operation.
