Description
General part information
TUSB8042A Series
The TUSB8042A is a four-port USB 3.2 x1 Gen1 (5Gbps) hub. The device provides simultaneous SuperSpeed USB, high-speed, or full-speed connections on the upstream port. The device also provides SuperSpeed USB, high-speed, full-speed, or low-speed connections on the downstream port. When the upstream port is connected to an electrical environment that only supports high-speed, full-speed, or low-speed connections, SuperSpeed USB connectivity is disabled on the downstream ports.
When the upstream port is connected to an electrical environment that only supports full-speed or low-speed connections, SuperSpeed USB and high-speed connectivity are disabled on the downstream ports.
The TUSB8042A supports per port or ganged power switching and overcurrent protection, and supports battery charging applications.
