UCC29002: Question about UCC29002

JAEHO CHOI
Prodigy 90 points
Part Number: UCC29002

Tool/software:

Hello.

I would like to Design by applying UCC29002 to Discharger Circuit of Battery. So, I'd like to ask you a few questions.

1) Why does it become a load share without FET Switching? and How does it work? about Load share

2) Due to the battery characteristics, Vin is variable  

   Is this the right application in this condition?

      1. Vin Range : 13 ~ 16.8V

      * Depending on the battery State of Charge

3) Is it possible for design with the below block diagram?

Thank you.

    Hi JaeHo,

    Unfortunately the load share controller works by modifying the feedback node of an SMPS (Switch-Mode Power-Supply). These can not force batteries to share. For better efficiency instead of diode OR-ing, you can look into our OR-ing controllers like the TPS2412 or maybe ideal diode controller like the LM74703.

    I hope this answers your question.
