The USB3803C-1-GL-TR is an USB 2.0 Hub Controller with three downstream ports. It can attach to an upstream port as a full-speed hub or as a full-/hi-speed hub and supports low-speed, full-speed and hi-speed (if operating as a hi-speed hub) downstream devices on all of the enabled downstream ports. It has been specifically optimized for mobile embedded applications. The pin-count has been reduced by optimizing the USB3803 for mobile battery-powered embedded systems where power consumption, small package size, minimal BOM and battery charger detection capabilities are critical design requirements. Standby mode and bypass mode power has been minimized. Instead of a dedicated crystal, reference clock inputs are aligned to mobile applications. Flexible integrated power regulators ease integration into battery powered devices. Automatic battery charger detection is available on the upstream port. All required resistors on the USB ports are integrated into the hub.
