Other Parts Discussed in Thread: BQ25606
We have seen intermittent failures with the bq24266 not charging the battery, and the system fails. The input voltage should be utilized when the battery level gets low, but we are seeing the Vout falling lower than the input voltage and the battery voltage dropping also. For example, last night a-a system went down. The Vinput was stable at +5V, but the battery voltage had dropped to 2.86V and the Vout was also at 2.86V. The part did not charge the battery and the Vout did not get the necessary voltage boost as expected. After removing the +5V and reapplying power, the system started to charge again and the Vout was back to its desired voltage. Any direction is appreciated, we are shipping units and concerned with the random failures we are seeing.
