Discussion - Hardware / FT230X USB Bus Powered with Power Switching Configuration
« on: October 09, 2020, 10:38:39 am »
Hello,
In the FT230X datasheet, there is an application description with switching the usb power with a MOSFET. I am wondering if this circuit actually works. I think it would just work if the CBUS3/PWREN# output switches between output low and hi-Z. But i couldn't find anywhere in the datasheet a description that this happens. If the output just switches to output high, the 3.3 V IO voltage wouldn't be enough to switch the MOSFET.
I am wondering how it works?
