Hi
The customer design the schematic, Power input 16V~25V, battery voltage 12.56V, charging current set 1.9A.
The query is charge current only 1A, modify the resistance can not increase the charging current, the charging indication is normal, STAT1 is 0V, STAT is 3.3V, and the charging current decreases toward the minor adjustment; confirm that the charging mode is fast charging.
Attached the schematic:
When charging, the inductance keeps ringing. Attached the BTST waveform:
PH waveform
Please give some suggestions.
Thanks
