TUSB3410: For intermal VDD18

Lee, Sam

Part Number: TUSB3410

Hi team,

Can you review the following schematic to use the internal regulator for VDD18 in TUSB3410? Is it okay to float VDD18/SUSPEND and to connect VREGEN to GND directly?

Thanks,

Sam Lee

Hello Sam,

It is okay to float the SUSPEND terminal; although I would recommend to add a couple of bypass capacitors (0.1uF and 0.01uF) to VDD18 and a PD resistor on VREGEN# (10K should be fine).
Other than that, your schematic looks good to me.
Regards,
Jorge
