OMAP3+TUSB1211, what to do with chip select?

Brad Caldwell

Other Parts Discussed in Thread: TUSB1211

I'm looking to use the TUSB1211 with OMAP3. My question is, what should I do with the chip select on the TUSB? OMAP will be a USB device and I'd like to have the TUSB in low power mode when a host is not connected via cable and active when a host is connected.

Thanks

Hello Brad,

You can use the CS pin the TUSB1211 to control it. CS is 1.8V pin so you will need to translate VBUS 5V indication to a 1.8V signaling a voltage divider but ratio needs to be selected carefully so it meets VBUS_valid spec.

Best regards,

Diego.
