Hi Sir,
Our customers using BQ25896 for their tablet product, and encountered a problem that a low pulse will occured with a period of about 40s. By checking the data sheet, we found that this problem is caused by the default 40s watchdog timeout, and there will be no such problem when we turn off the watchdog.
But we cannot turn off the watchdog in actual applications. So we are trying to set an interval of 10s to check the watchdog timeout time, but it does not take effect. Can u give us some suggestion for this problem?
The charging waveform is shown as below:
Thanks,
Best Regards
