Greetings...
Please, I need help in fixing the above board problem. The board number is DAY11AMB6E0 REV: E.
0.8V is the voltage that was able to deliver into the system due to ACDRV being stuck at 0.8V. The system works when 19V is introduced to the PQ20 drain, but the battery does not charge.
Below is the IC's reading when plugged in:
1. 0.8
2. 0.8
3. 0.8
4. 0.8
5. 0
6. 1.6
7. 0.4
8. 0.5
9. 0.5
10. 0
11. 1.9
12. 1
13. 1
14. GND
15. 0
16. 6
17. 5.9
18. 0
19. 1
20. 19.7
There is no break between PR 211, 137 and the IC.
Attached is the schematics diagram of the charging IC: BQ24738H
