Part Number: TPS2046B Hello TI community! I have problem with EMI. If ESD sparks near the device then USB reinitialize itself. What should I do to prevent the usb reinitializetion?
Dear Bing,
Thank you for your support.
(Sun Young is my customer.)
the biggest problem is that if they make overcurrent situation over about 3 seconds, TPS2044A cannot recover to normal status.
(You can see the waveform on 2nd slide of pptx file.)

I checked the CC1/CC2 voltage rating is up to Vcc(3.3V).
But the reference circuit uses TPS2046B to coonect a 5V rail to CC1 and CC2 while VCTRL1/VCTRL2 is low.
Is the setting correct…
