TPS2411PW Datasheet PDF - TI

The TPS2411PW. is a N+1 and ORing Power Rail Controller in conjunction with an external N-channel MOSFET, emulates the function of a low forward-voltage diode. It can be used to combine multiple power supplies to a common bus in an N+1 configuration, or to combine redundant input power buses. The TPS2411 has an on/off control method. Often have either N+1 redundant power supplies, redundant power buses, or both. These redundant power sources must have the equivalent of a diode OR to prevent reverse current during faults and hotplug. A TPS2411 and N-channel MOSFET provide this function with less power loss than a schottky diode. Accurate voltage sensing, programmable fast turn-off threshold and input filtering allow operations to be tailored for a wide range of implementations and bus characteristics.
