open-in-new Find other Ideal diode/ORing controllers

Description

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.

A number of monitoring features are provided to indicate voltage bus UV/OV, ON/OFF state, and a shorted MOSFET gate.

Description
The TPS2411EVM-096 allows reference circuit evaluation of TI's TPS2411 ORing controller devices. The TPS2411 devices control an external N-channel MOSFET in a typical ORing application and can be used to control two back-back connected MOSFETs to support over voltage and under voltage protection.
Features
  • Dual channel Oring control from 0.8V to 16.5V
  • Support standard Oring configuration and back-back MOSFET operation for bidirectional blocking also
  • Programmable over voltage cutoff and under voltage
  • On board LED provide indication of operating status and fault conditions
