Hot plug controllers reduce telecomms down time

Edited by the Electronicstalk editorial team Nov 29, 2002

The new Endura ISL6141, ISL6142, ISL6151 and ISL6152 hot-plug ICs are designed specifically for systems requiring high levels of power protection and reduced down time.

The new Endura ISL6141, ISL6142, ISL6151 and ISL6152 hot-plug ICs are designed specifically for systems requiring high levels of power protection and reduced down time, and allow failed line cards and communications modules to be replaced or upgraded while the system remains live and fully operational.

Applications for Intersil's new hot-plug controllers include protection for cards and modules with hot swap capability in central offices, PBXs, digital subscriber line access multiplexers (DSLAMs), digital loop remote terminals, voice over Internet protocol (VoIP) routers, wireless base stations, Internet traffic routers, optical networking equipment and file servers.

These negative voltage controllers operate over a -20 to -80V range (-100V maximum) with undervoltage and overvoltage protection to prevent startup before power is stable.

IntelliTrip dual-level current limiting provides accurate current limiting for 600us before shutdown during a fault or quick shutdown followed by a single soft start in the event of a hard fault (4X overcurrent limit).

The ISL6142/52 devices offer additional programmable current limit duration.

They also feature a soft start to eliminate startup current surges and an improved power-good indicator monitors both drain and gate voltages to make decisions on protection.

Industrial temperature range devices are available for extreme environments.

The ISL6142 and ISL6152 offer a real-time load-current monitor to accurately determine power dissipation in the load without the need for a resistor in the current path.
