Other Parts Discussed in Thread: BQ25758, LM5171,
Tool/software:
Hello,
We are interested in using the BQ25756 chip to try and create a bidirectional 100 Amp DC/DC.
We see the BQ25756 chip seems to be limited by the battery charging sense resistor (5m @ 10 amp max) and the input sense of 2m at 20 A. We would like to see about increasing this, is it possible to decrease the sense resistor values with just less accuracy?
We would also be open to paralleling multiple chips. Our concern would be, could they parallel and operate in reverse mode? Possibly by setting a master at a slightly higher voltage than the slave chips to force them into constant current mode under a draw?
Thank you in advance for any clarification you can provide.
V/r
