Other Parts Discussed in Thread: TPS2549
Hi,
I want to use a USB power switch which has no ID pin on USB2.0 HOST connector. Will be using as OTG like without ID pin.
When I use a device (like flash memory) or PC/laptop on USB port, Switch IC should not be effected any power conflict by sensing external power.
Additionally, it should have a function like "external power detected on a port" output. So, I can switch microprocessor to download new code mode.
Could you please help to select a switch IC?
For example, TPD4S214 seems suitable to do it.
Thanks.
Ali
