Tool/software:
Hi team,
In the following TUSB320LAI datasheet note that, if I2C is pull up to 3.3V, VDD need to be 3.0V and above.
Customer now I2C pull up voltage is1.8V, since our TUSB320LAI VDD power supply range is 2.7V ~5V, does it OK for them to keep I2C 1.8V pull up work while VDD power supply is off?
Does the 1.8V I2C pull up voltage get risk to back power the device?
Regards,
Will
