ON controllers verified to meet IEEE802.3at

ON Semiconductor's NCP1081 and NCP1083 integrated Power-over-Ethernet Powered Device (PoE-PD)/DC/DC convertor controllers have been verified to meet the upcoming IEEE802.3at standard.

Both devices have passed the IEEE 802.3af standard tests and have also been verified by the University of New Hampshire Interoperability Laboratory (UNH-IOL) for the recent draft IEEE 802.3at (D3.1) standard, which includes a test of the two event physical layer classification.

The UNH tests confirm that these devices can enable PoE+ compliant platforms on the market, and are in line with the evolving high-power requirements of the WLAN access point, WIMAX, industrial and IP camera markets.

ON Semiconductor's portfolio of integrated PoE-PD products contains four devices.

The NCP1081 and NCP1083 provide power levels up to 25.5W for applications in line with the draft IEEE 802.3at (D3.1) standard and up to 40W for proprietary high-power PoE applications.

The NCP1080 and NCP1082 offer IEEE802.3af-compliant power levels.

The NCP1082 and NCP1083 are also capable of providing power via an auxiliary parallel supply.

The NCP1080/1/2/3 are pin-compatible and offered in a TSSOP-EP 20-pin package.

This feature allows the customer to mix-and-match different PoE capabilities on different platforms.

The PoE-PD portfolio utilises ON Semiconductor's automotive-qualified, high-voltage SmartPower process to provide superior cable electrostatic discharge and surge protection levels compared to other integrated PoE-PD/DC/DC convertor controllers.

Low on-resistance and extended temperature range from -40C to 85C with full operation up to 150C junction temperature allows these PoE-PD controllers to achieve high power levels while operating in harsh environments.
