The device can be used to bine multiple power supplies to a mon bus in an N+1 configuration, or to bine redundant input power buses. The TPS2410 provides a linear turn-on control while the TPS2411 has an on/off control method. Applications for the TPS2410x include a wide range of systems including servers and tele. These applications 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 TPS241x 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. A number of monitoring features are provided to indicate voltage bus UV/OV, ON/OFF state, and a shorted MOSFET gate.
