IR5001STRPBF Product details

DESCRIPTION

The IR5001S 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 IR5001S 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 IR5001S 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. Typical turn-off delay for the IR5001S is only 130nS, which helps to minimize voltage sags on the redundant dc voltage.



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 continuous gate short conditions

Integrated voltage clamps on both comparator inputs allow continuous application of up to 100V

Option to be powered either directly from 36-75V universal telecom bus (100V max), or from an external bias supply and bias resistor

Input/Output pins to determine the state of the Active ORing circuit and power system redundancy



APPLICATIONS

-48V/-24V Input Active ORing for carrier  class communication equipment

Reverse input polarity protection for  DC-DC power supplies

24V/48V output active ORing for  redundant AC-DC rectifiers

Low output voltage (12V, 5V, 3.3V...)  active ORing for redundant DC-DC and AC-DC power supplies

Active ORing of multiple voltage regulators for redundant processor power
