Jacky,
1) Assuming you refer to +5v input with jumper J8 tying this to Vdd on the TPS2413, you can use Vin of 3.3v to 4.5v you note.
2) RSET is a resistor to GND to program the reverse current detect threshold to shut off the pass MosFET. You should…
Hi Pao,
Thank you for considering our part in your application. The TPS2412 is a linear gate control device. Meaning, it tries to keep the voltage across the FET at around 10mV or higher.
1) Vsd > 10mV, Gate goes up (until max of Vin + 10.2V)
2…
Other Parts Discussed in Thread: TPS2413 , TPS2412 I have designed a board that takes in power from 5 power supplies at 5VDC rated at 60A each and they are OR'ed together to have one output Vout at 5VDC . I attached the schematic in PDF form.
The MOSFET…
HI Watanabe-san,
The TPS2412 employs linear gate control. Meaning it tries to maintain a 10mV (V AC ) across the FET. As such, the V GS seen will vary as a function of the load current. So yes, this is not well defined in the datasheet. As the load…
Hello Tommy,
Thank you for your interest in the UCC29002 load-share controller.
In your post text and diagram, there are references to part numbers that I cannot find on TI.com: TPS5412, LM3363D, LM33630. I believe that you mean TPS2412 and LMR33630…
Hi Jiabin,
A single UCC28951 is more than sufficient to support 12-V OUT at 300-W. You can easily do this with one controller. If you do choose to use multiple controllers, here is an application note showing how to use the Synch pin to create a leader…
Hi Mikail,
I am sharing an application note which shown how to achieve Current Sharing in Redundant Systems using UCC39002+TPS2412.

Right now we do not have a controller which has integrated load sharing + ORing functions…
Hi WB,
Regarding your question on ORIng + Load Current sharing, you can have a look at Current Sharing in Redundant Systems App note.
You can consider using TPS241x instead of LM74700 as TPS241x has programmable reverse current threshold and is…
Hello,
I reviewed your schematics an application note and have the following comments.
1. The UCC29002 was designed for load sharing two power supplies operating in parallel.
A. Please refer to figure 2. Current Sharing in Redundant Systems.pdf…
