We are currently developing equipment using BQ24092DGQ.
The LED lights up at regular intervals by operating the CPU at a later stage while charging.
If the lighting cycle of the LED is shortened, the BQ24092DGQ will not complete charging.
(5s 37.5% lit→5s 2.5% lit)
Since ISET has a resistance of1.8K, we understand that the fast charge will be 300mA and the end-of-charge current willbe3 0 mA.
The current is less than3 0 mA even when charging is not detected.
However, since the LED is lit with PWM, the current is unstable.
If the LED lighting cycle is lengthened (25s 25% lit→5s 1% lit) the charge can be detected.
Please let me know if there are conditions for charging completion.
Current, voltage, time, etc...
