I have made a PCB to test the BQ24196. But I have met several questions.
1. The maximum charge current of my board for my phone is 800mA while the nominal maximum charge current of BQ24196 is 2.5A. But I moved BQ24196, the charge current is normal. The schemic can refer to below.
2. When I read the register REG08 of the chip, I find its values change unexpectedly after I power up my PCB for about 20 seconds. For example, PG _STAT changes from 1 to 0 while CHRG_STAT changes from 10 to 01.
