... INN and INP pins to the source and drain terminals of the N-FET should be as short as possible. The (INP – INN) voltage difference determines the state of the Vout pin of the IR5001. When the body diode of the Active ORing N-FET is forward- biased and the current first starts flowing, the voltage difference INP – ...

... In the IR5001, the FETch pin is an input pin that can be used to turn off the output of the IR5001: logic high signal on FETch will pull the Vout pin low, and turn-off the channel of the Active ORing N-FET. This will force the current to flow through the body diode, resulting in VINP – ...

... However, any of the biasing schemes shown in Fig. 16 can be used. For input ORing in carrier-class communications boards, one IR5001 is used per feed. This is shown in Fig.1. An evaluation kit is available for typical system boards, with input voltages of negative 36V to negative 75V, and for power levels from 30W to about 300W ...

... FET. PCB trace between the Vout pin and the gate of the N-FET should also be minimized. A minimum of 0.1uF decoupling capacitor must be connected from Vcc to Gnd of the IR5001and should be placed as close to the IR5001 as possible. Ground should be connected to the source of N-FET separately from the INP pin. ...
