TheXR22404 is a USB 2.0, 4-port hub that can be configured for downstream device charging and is compatible with Battery Charging specification revision 1.1/1.2.\nThe upstream USB interface has an integrated USB 2.0 PHY and device controller that is compliant with both hi-speed (480Mbps) and full-speed (12Mbps) and downstream PHY supporting hi-speed, full-speed and low-speed (1.5 Mbps) on each of the 4 downstream ports.\nThe XR22404 provides ganged power control and global overcurrent sensing for the downstream ports.\nThe XR22404 may be operated from either 5V or 3.3V. If powered from 5V internal regulators provide 3.3V and 1.8V used internally by the device. Port activity and overall hub activity indicators provide status outputs for external LEDs. An external I2C EEPROM may be used with the XR22404 to configure USB device descriptors.\n
