Hi, Team
My car infotainment customer is using TPS2549 in their infotainment system. CTL1/2/3 are all pull high for CDP mode. When system start up, i.MX6 will set a 700mV pulse on DP_OUT/DM_OUT pins, and that will cause OUT pin discharge. There is NO USB device connected to the USB port.
Why the OUT pin will dischcarge?
How can we make the OUT pin stable even there is pulse on DP_OUT/DM_OUT pins just as below?
CH1: DP_OUT
CH2: DM_OUT
CH1: DP_OUT
CH2: OUT
Thanks
Kevin Zhang
