Hi,
I am designing a wearable using BQ25120AYFPR, but having problem that microcontroller can't communicate through I2C. Microcontroller has pullup internal 11k-13k ohm so it should fine. I have another 2 devices connected to I2C bus, but only 2 of them are detected by microcontroller. ( I also build another PCB without those 2 devices, but still microcontroller can't communicate).
VSYS i want to use is by default 1.8V, so pullup internal is about the same.
I am aware about startup delay 70mS or more, and no success.
Please check my schematic if I am doing wrong and miss something there. Is there any solution or idea to solve this? should I share the code in microcontroller if needed.
Thank you very much
