Power over Ethernet (PoE) is a widely adopted technology used to transfer power and supply the powered device (PD) including wireless access points, VoIP phones and even LED bulbs over an RJ-45 cable also carrying data as described in the IEEE 802.3 standard and its evolutions including IEEE 802.3bt, IEEE 802.3at and IEEE 802.3af.

We provide a range of products providing a complete interface with all the functions required by the communication standard including detection and classification as well as protection features including under-voltage lockout (UVLO) and in-rush current limitation. In addition, these products can control Hot-swap power MOSFETs that can greatly simplify the development of IEEE 802.3 compliant solutions for powered devices (PD).
