Description
General part information
TPS2411 Series
The TPS241x controller, in conjunction with an external N-channel MOSFET, emulates the function of a low forward-voltage diode. The device 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 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 telecom. 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.
