Full Featured N+1 and ORing Power Rail Controller

FEATURES

DESCRIPTION

•

Control External FET for N+1 and ORing

Wide Supply Voltage Range of 3 V to 16.5 V

Controls Buses From 0.8 V to 16.5 V

Linear or On/Off Control Method

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.

Internal Charge Pump for N-Channel MOSFET

Rapid Device Turnoff Protects Bus Integrity

Positive Gate Control on Hot Insertion

Soft Turn on Reduces Bus Transients

Input Voltage Monitoring

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.

N-channel MOSFET provide this function with less

power loss than a schottky diode.

Shorted Gate Monitor

MOSFET Control-State Indicator

Industrial Temperature Range: –40°C to 85°C

APPLICATIONS

•

N+1 Power Supplies

Server Blades

Telecom Systems

High Availability Systems

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.
