The maximum current rating for each USB port is 2.5A, but it's recommended to limit it to 1.5A for reliable operation.
The device is configured for USB 2.0 or USB 3.0 mode through the MODE pin. A logic high on the MODE pin selects USB 3.0 mode, while a logic low selects USB 2.0 mode.
The EN pin is an active-high enable input that allows the device to be enabled or disabled. When EN is high, the device is enabled, and when EN is low, the device is disabled and consumes minimal power.
The device requires a specific power sequencing to ensure proper operation. The recommended power-up sequence is VCC, then VBUS, and the recommended power-down sequence is VBUS, then VCC.
The device has a maximum junction temperature of 125°C. To ensure reliable operation, it's recommended to keep the device temperature below 85°C. This can be achieved by providing adequate heat sinking and airflow.
