LTC4263-1 Datasheet High Power Single Pse Controller

Manufacturer: Linear Technology (now Analog Devices)

Overview: LTC4263-1 High Power Single PSE Controller with Internal Switch.

General Description

The LTC®4263-1 is a high power, single PSE controller for use in Power over Ethernet systems.

The internal current limit and short-circuit protection are designed to provide up to 30W of PSE output power for power hungry PoE applications such as WAPs, security cameras and RFID readers.

The LTC4263-1 includes IEEE 802.3af pliant PD detection circuitry along with selectable AC and DC disconnect sensing, allowing seamless operation in conventional IEEE 802.3af systems as well as propriety, high power applications.
