Product Details
The LTC4263-1 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 compliant 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. The LTC4263-1 simplifi es PSE implementation, needing only a single supply and a small number of passive support components. Onboard control algorithms provide complete PSE functionality without the need of a microcontroller and built-in foldback and thermal shutdown provide comprehensive fault protection. An LED pin indicates the state of the port and detection backoff timing is confi gurable for either endpoint or midspan operation.
The LTC4263-1 is available in a miniature 14-pin 4mm × 3mm DFN package.
Applications
- High Power Endpoint/Midspan PSEs
- Single-Port or Multi-Port Power Injectors
- Low Port Count PSEs
- Environment B PSEs
- Standalone PSEs
