Hi Teja,

Schematic looks good!

One thing to note with regard to sequencing, is if you are ever pulling ON high when Vin/Vbias is low, we want to be sure Vbias is at least 2.5V tD (ON delay time) after Von is at 50% to be sure the device is biased correctly.

Best Regards,

Elizabeth

Hi Elizabeth,

Thanks for your valuable feedback. Regarding sequencing the VCC_SYS_3V3 will be turned on first. After that on the next sequence only We can get the enable signal of the VCC_AM_SYS_3V3. Vbias will be 3.3 as it is connected to Vcc IN, Then only after the Next sequence this enable signal will encounter and the device will start working. I think from the above approach there is no issue with the Sequencing, Please correct me if I am wrong. Share your feedback with us.

Thanks and Regards,

- Teja
