I'm designing a lithium battery charging circuit and I'm using BQ24090. My schematic as below:
I am expecting to have 500mA charging current at 5V, however, I am only able to get 400mA. My lithium battery is at 3.68V and I am using a DC power supply (lab bench type) to charge the battery.
Anything that I could do to increase the charging current to 500mA? I think with the R1 of 540 ohm, I should be able to get 1A charging current.
Thank you very much!
