Part Number:BQ24650
Hi team,
Within our application, the bq24650 blinks periodically STAT1 & 2 with the following cycle steps :
| STEP number | STAT1 | STAT2 | Supposed charge state |
| 1 | ON | OFF | Charge in progress |
| 2 | OFF | ON | Charge complete |
| 3 | ON | ON | Fault (?) |
| 4 | - | - | Go back to step 1 |
For a better understanding of the situation and the time elapsed between each steps, please take a look at this video
The cycle period is slower when current is lower.
Nominal battery voltage is 12V and lead acid. During the video, the voltage is around 13.3V so we assuming battery is fully charged.
Our question : Is it a normal situation ? Because we assume when battery charging is completed, charge complete state should be idle and stable.
Regards,
Maxime.
