Other Parts Discussed in Thread: TEST
Hi we have BQ7791501 based BMS under production and facing major issue of under voltage cutoff/threshold, which is mentioned as 2800mV in Datasheet but in actual we are getting different UV cutoff in different boards, we tested 100+ boards but getting same issue.
Earlier at R&D time, everything worked fine, All cuttoff's were ok, UV cutoff was around 2770, 2780,2800mV, but now we are getting it 2850, 2880 & upto 2940mV also.
We are using Auto grade parts.
We want to know which part can affect Under Voltage cutoff.
Why we are getting UV cutoff at 2940mV?
We are using recommended circuit only, please help to diagnose problem & provide solution as soon as possible.
