Product Overview
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 upto 30W of PSE output power for power hungry PoE applications such as WAPs, security cameras and RFID readers. It 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. It simplifies 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. It is used in applications such as high power endpoint/midspan PSEs, single-port or multi-port power injectors, low port count PSEs, environment B PSEs, standalone PSEs etc.
- Internal MOSFET with thermal protection
- Precision inrush control with internal sense resistor
- Forced current PD detection for noise immunity
- AC and DC disconnect sensing
- Legacy PD detection, robust short-circuit protection
- Pin-selectable detection backoff for midspan PSEs
- LED driver indicates port on and blinks status codes
- Supply voltage is 48V typical at (VDD48 - VSS, TA = 25°C, VDD48 - VSS = 48V)
- Operating ambient temperature is -40°C to 85°C
- Package style is 14-lead plastic DFN
