Hello,
In the following method, the customer detect timer fault.
Could you please let me know this reason?
In this case, is the timer cleared and start recharge when the battery voltage decrease to under V(RCH)?
Install a Li battery on the board using the device, supply USB power with the power on, and charge it at the same time.
1. Charging the battery and it becomes "Charge Done" when it is fully charged.
2. In "Charge Done" state, stop charging from USB once.
(Pull out the USB cable at one end)
3. Insert the USB cable and charge again. At this time, the status will be "Fast Charge".
4. If they continue to charge the battery as it is, it becomes "Charge Suspend" with the charge time timer (set to 10h).
⇒ It does not become "Charge Done".
Best Regards,
Ryuji
