Other Parts Discussed in Thread: TIDA-00588
We're using BQ25570 in our product. Currently we are having problems with this IC. Devices are sent back by customers to claim a lot of warranty. I checked the VBAT pin of IC BQ25570 is higher than 4.2V (4.5 - 4.8V). Common value is about 4.18V. This IC is are charging for 18650 cells, so the 18650 cells broken and the device stopped working. I want to find out what could be the cause of VBAT pin higher than 4.2V. I refer to the design according to TIDA-00588
