Description

The TPS2412/13 controller, in conjunction with an external N-channel MOSFET, emulates the function of a low forward voltage diode. The TPS2412/13 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 TPS2412 provides a linear turnon control while the TPS2413 has an on/off control method.

Applications for the TPS2412/13 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. Redundant power sources must have the equivalent of a diode OR to prevent reverse current during faults and hotplug. A TPS2412/13 and N-channel MOSFET provide this function with less power loss than a schottky diode.

Accurate voltage sensing and a programmable turnoff threshold allows operation to be tailored for a wide range of implementations and bus characteristics. The TPS2412/13 are lower pin count, reduced feature versions of the TPS2410/11.

Description

The TPS2412EVM is an evaluation module set up to wire-OR two power supplies for redundant power to a load using two TPS2412s and MOSFETs.

Features

The 5 V supply is jumper selected to power VDD on the TPS2412s and the glitch circuit if the control voltage is less than 3.0 V. The Glitch maker, discussed in the test methods section of the User's Guide, applies a 1 ohm load to the input supply for 1 ms. This disruption allows (...)
