Hi,
Will my application below cause any of the issues as stated in section 11.1 of the datasheet?
For UART transmit direction, the power-up sequence didn't comply with section 11.1 where VCCB is powered up before VCCA.
Note: V1P8S always comes before V3P3S.
Section 11.1 : A proper power-up sequence always should be followed to avoid excessive supply current, bus contention, oscillations, or other anomalies.
To guard against such power-up problems, take the following precautions:
1. Connect ground before any supply voltage is applied.
2. Power up VCCA.
3. VCCB can be ramped up along with or after VCCA."
