DESCRIPTION
The TPS2410/11 controller, in conjunction with an
external N-channel MOSFET, emulates the function
of a low forward-voltage diode. The TPS2410/11 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 TPS2410/11 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 TPS2410/11 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.
