Part Number: BQ25606
Hello,
I made a charger based on BQ25606 IC charger. Schematic is below:
Current limited power supply (5V) is connected to VBUS_IN pin, battery is connected to VBAT_IN pin. During charge process I can see that current from power supply is around 1.4 A which is normal. STATE pin is low and this is also normal - this means that charging process is active. When battery reaches approx. 4.2V current slowly drops to around 10mA but STAT pin still stays at zero. It looks like that charging process doesn't finish. What could be reason for this?
Many thanks,
Kind regards,
Dejan.
