Full Featured N+1 and ORing Power Rail Controller
• Control External FET for N+1 and ORing
The TPS2410/11 controller, in conjunction with an
• Wide Supply Voltage Range of 3 V to 16.5 V
external N-channel MOSFET, emulates the function
• Controls Buses From 0.8 V to 16.5 V
of a low forward-voltage diode. The TPS2410/11 can
• Linear or On/Off Control Method
be used to combine multiple power supplies to a
common bus in an N+1 configuration, or to combine
• Internal Charge Pump for N-Channel MOSFET
redundant input power buses. The TPS2410 provides
• Rapid Device Turnoff Protects Bus Integrity
a linear turn-on control while the TPS2411 has an
• Positive Gate Control on Hot Insertion
on/off control method.
• Soft Turn on Reduces Bus Transients
Applications for the TPS2410/11 include a wide range
• Input Voltage Monitoring
of systems including servers and telecom. These
applications often have either N+1 redundant power
• Shorted Gate Monitor
supplies, redundant power buses, or both. These
• MOSFET Control-State Indicator
redundant power sources must have the equivalent of
• Industrial Temperature Range: – 40 ° C to 85 ° C
a diode OR to prevent reverse current during faults
and hotplug. A TPS2410/11 and N-channel MOSFET
• Industry-Standard 14-Pin TSSOP Package
provide this function with less power loss than a
schottky diode.
• N+1 Power Supplies
Accurate voltage sensing, programmable fast turn-off
threshold, and input filtering allow operations to be
• Server Blades
tailored for a wide range of implementations and bus
• Telecom Systems
characteristics.
• High Availability Systems
A number of monitoring features are provided to
indicate voltage bus UV/OV, ON/OFF state, and a
shorted MOSFET gate.
