DESCRIPTION

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. Typical

turn-off delay for the IR5001 is only 130nS, which helps to

minimize voltage sags on the redundant dc voltage.

input contain integrated high voltage resistors and internal

clamps. This makes the IR5001 suitable for applications at

voltages up to 100V, and with a minimum number of

external components.

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
