TUSB7320: PWRON and OVERCUR Outputs

juanma cc

Part Number: TUSB7320
Other Parts Discussed in Thread: TPS2560

Hi everyone, I´m reading the TUSB7320 documentation, and, in my schematics, I'm not using these outputs, but on the recommended circuit schematic these are been used and controlled with TPS2560. What is the problem if I don't use TPS2560? In which cases are needed?

Thank you so much!

Hi,

Vbus power switch should be used such that the USB host controller can disable VBUS based on SW or if problem is indicated with USB port. Overcurrent reporting is needed to be fully USB compliant.
