TPS2410

TPS2411

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.
