TUSB1310A: Reset happening from VBUS pin voltage drop

Part Number: TUSB1310A

Hello team,

I received a inquiry about reset happening on TUSB1310A.

[Question]

What is the threshold for detecting the on/off of the VBUS pins?

[Background]

I heard that VBUS pin is used to determine whether VBUS is connected or not.

The customer circuit seems to be causing reset due to the voltage drop to the VBUS pin.

I want to know how much the VBUS pin should be maintained to prevent it from causing an device stop.

Please contact us if there are other information needed, or if I was misunderstanding about the device.

Best Regards,

Ryotaro Fukui
