Higher-Power PoE for Applications Up to 40W

The NCP1080 and NCP1081 Power-over-Ethernet Powered Devices (PoE-PD) provide an integrated solution for demanding Ethernet applications.

In a single unit, they combine an enhanced PoEPD interface and a configurable DC/DC converter controller.

The NCP1080 is IEEE 802.3af compliant and serves the 13W segment of the market. The NCP1081 is a high-power PoE device, which supports the most recent IEEE 802.3 (draft 3.0) specifications at 25W, and has been designed to support higher-power proprietary applications up to 40W. These higher-power features mean that the advantages of PoE are being made available to amuch broader spectrum of products.

Both devices are pin compatible and fabricated in a robust, rugged high-voltage process suitable for the most demanding environments. The NCP1080 and NCP1081 are capable of withstanding hot swap, surge and cable-ESD events.

 

FEATURES Supports IEEE 802.3at (draft 3.0) two-event Layer 1 classification High-power Layer 1 classification indicator Extended power ranges up to 40W Programmable operating current limit up to 1100mA -40°C to 85°C industrial temperature range with full operation up to 150°C junction temperature Cable-ESD robustness above 3kV

APPLICATIONS VoIP communications WLAN access points andWimax base stations IP cameras Industrial Ethernet applications: HMI, sensors, IO modules Point-of-sale devices RFID base stations
