Hello,
I am using the MP2667 charger/power path chip where the schematic design was made according to the evaluation board. There is one thing that does not seem right:
When first powered on or when exiting shipping mode, the first I2C transfer always fails.
I am aware that there is an immunity timer of 200us when power is first applied, but this issue also happens if I add a delay before writing to the chip. -Is this expected behaviour or am I doing something wrong?
Regards,
Sven Forsberg
