PIN DESCRIPTIONS
Note 1:
Guaranteed by design but not tested in production.
Note 2:
Low Vcc output voltage corresponds to low UVLO voltage

PIN SYMBOL
PIN DESCRIPTION
1
Vline
IC power supply pin for 36V to 75V input communications systems.
Minimum 25V has to be applied at this pin to bias the IC.
2
Vcc
Output pin of the internal shunt regulator, or input pin for biasing the IC via
external resistor. This pin is internally regulated at 12.5V typical. A
minimum 0.1uF capacitor must be connected from this pin to Gnd of IR5001.
3
FETch
FET check input pin. Together with FET status output pin, the FETch pin
can be used to determine the state of the Active ORing circuit and power
system redundancy.
4
FETst
FET status output pin. Together with FETch input pin, the FETst pin can be
used to determine the state of the Active ORing circuit and power system
redundancy.
5
INP
Positive input of internal comparator. This pin should connect to the source
of N-channel Active ORing MOSFET.
6
INN
Negative input pin of internal comparator. This pin should connect to the
drain of N-channel Active ORing MOSFET.
7
Gnd
Ground pin of the IR5001.
8
Vout
Output pin for the IR5001. This pin is used to directly drive the gate of the
Active Oring N-Channel MOSFET.
