Hello,
We plan to use the BQ27742-G1 protector and fuel gauge. I have been reviewing the specification but there is something that puzzles me...
Apparently, there are 2 levels of protection: hardware based and firmware based, both having their dedicated configuration registers. The specification boasts voltage hardware based protections include both over-voltage protection and under-voltage protection. There is indeed a note for the delay of under voltage hardware protection (specification page 5, table 4, 31.25ms), however, I can't find where to program said hardware based under-voltage protection. The hardware based over voltage protection is programmed through the Config OV Prot register, but it looks like there is no equivalent for hardware under-voltage protection... Unless setting the Config OV Prot register also sets the hardware under-voltage protection at the same time.
Could someone bring some insights on this matter?
