Dears：
We debug our TUSB544‘s Board, and there is an issue about our board of TUSB544 as below:
1. If firstly step is TUSB544 is not powered on with 3.3V, secondly AUXn is pulled up with 3.3V, thirdly SLP_SO and I2C is pulled up, the last TUSB544 is powered on with 3.3V .
Is there any issue about this method?
2. If firstly step is TUSB544 is not powered on with 3.3V, secondly AUXn is pulled up with 3.3V, thirdly we check the Pin of SS has signal, fourthly SLP_SO and I2C is pulled up, the last TUSB544 is powered on with 3.3V .
Is there any issue about this method?
Anyway, is there any issue about the below method:
We will pull up SS, IIC, SLP_S0 before we power on TUSB544 with 3.3, and the right method about the Power on Sequence?
I look forward to hearing from you, thanks!
Best regards
