Hi,
We face an problem that the MIC voltage is not match with VBUS voltage.
We set register 0x13 = 0x4A, and measure MIC pin, the voltage is 1.7V. But the voltage of VBUS is 0.6V~0.2V, and would keep bounce.
If we add a 1M ohm on ID pin, the VBUS voltage will be 1.7 V.
Why?
Could we set register to get stable 1.7V?
Below are register dump, pic1 is VBUS unstable, pic2 is VBUS stable. The only difference is 0x02. Is this setting the root cause?
Thanks
