OTG USB

Hello guys,

 

I need to design a system to work as both host and device in mass storage class. That means the board should be able to act as device to be connected to the PC or as host powers/enumerate a usb stick. I wonder if OTG usb is a proper solution for this type of application or not?

We found that MAX3353 provides only 8mA on Vbus which definitely is not enough to power a USB stick.

 

Cheers
