PIN DESCRIPTION

IC power supply pin for 36V to 75V input communications systems.

Minimum 25V has to be applied at this pin to bias the IC.

Output pin of the internal shunt regulator, or input pin for biasing the IC via

Vcc

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.

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.

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

redundanc y .

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.
