TUSB2E221: Is resetB pin always high okay?

In addition, how to set different I2C address? we need to inform BU before the shipment?

Thank you

Charles

For example, if customer want to use 2*eUSB device in same I2C line, then they need to use different part number to distinguish different I2C address? can we achieve this by having some special pin assignment? 

Hi Charles,

customer want to know if they don't want to control TUSB2E221 reset pin, can they just pull high resetB? any risk in such application?

I would recommend following the EVM schematic for this application, with a .1uF pulldown and a 2.2Kohm pull-up:

For different I2C addresses, yes, you will need to reach out to the BU to have a device OTP'd with a different I2C address.

Thanks,
