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. Typical
turn-off delay for the IR5001 is only 130nS, which helps to
minimize voltage sags on the redundant dc voltage.
Both inputs to the IC (INN and INP) as well as Vline
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.
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
-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
