The VDDIO pins of the TUSB1210 supply 1.8 V (nominal) power to the core of the TUSB1210. This power rail can be isolated from all other power rails by a ferrite bead to reduce noise.
The VBAT pin of the TUSB1210 supply 3.3 V (nominal) power rail to the TUSB1210. This power rail can be isolated from all other power rails by a ferrite bead to reduce noise.
The VBUS pin of the TUSB1210 supply 5.0 V (nominal) power rail to the TUSB1210. This pin is normally connected to the VBUS pin of the USB connector.
