IR5001 - UNIVERSAL ACTIVE ORING CONTROLLER

Description

The IR5001 is a universal high-speed controller and N-channel power MOSFET driver for Active ORing and reverse polarity protection applications.

The output voltage of the IR5001 is determined based on the polarity of the voltage difference on its input terminals.

Features

  •   Controller / driver IC in an SO-8 package for                 implementation of Active ORing / reverse polarity protection using N-channel Power MOSFETs Suitable for both input ORing (for carrier class telecom equipment) as well as output ORing for redundant DC-DC and AC-DC power supplies 130ns Typical Turn-Off delay time 3A Peak Turn-Off gate drive current Asymmetrical offset voltage of the internal high-speed comparator prevents potential oscillations at light load Ability to withstand conti.

Data Sheet No.PD60229 IR5001 UNIVERSAL ACTIVE ORING CONTROLLER DESCRIPTION The IR5001 is a universal high-speed controller and N-channel power MOSFET driver for Active ORing and reverse polarity protection applications. The output voltage of the IR5001 is determined based on the polarity of the voltage difference on its input terminals. In particular, if the current flow through an N-channel ORing FET is from source to drain, the output of the IR5001 will be pulled high to Vcc, thus turning the Active ORing FET on. If the current reverses direction and flows from drain to source (due to a short-circuit failure of the source, for example), the IC will quickly switch the Active ORing FET off.
