The TUSB8044A supports per port or ganged power switching and over-current protection, and supports battery charging applications. An individually port power controlled hub switches power on or off to each downstream port as requested by the USB host. Also when an individually port power controlled hub senses an over-current event, only power to the affected downstream port will be switched off. A ganged hub switches on power to all its downstream ports when power is required to be on for any port. The power to the downstream ports is not switched off unless all ports are in a state that allows power to be removed. Also when a ganged hub senses an over-current event, power to all downstream ports will be switched off.
A platform that implements both a USB 3.2 Gen 1 x 1 hub and a USB 2.0 hub with Billboard.
