LT LTC4263CS#PBF

控制器（PSE）15.4 W802.3af（PoE）

Overview

The LTC4263CS is an autonomous single-channel PSE controller for use in IEEE 802.3af compliant Power over Ethernet systems. It includes an on-board power MOSFET, internal inrush, current limit, and short-circuit control, IEEE 802.3af compliant PD detection and classification circuitry, and selectable AC or DC disconnect sensing. On-board control algorithms provide complete IEEE 802.3af compliant operation without the need of a microcontroller. The LTC4263CS simplifies PSE implementation, needing only a single 48V supply and a small number of passive support components.

The LTC4263CS is available in 14-pin 4mm × 3mm DFN and 14-pin SO packages.
