USB2513BI-AEZG Datasheet PDF - Microchip

●The USB2513BI-AEZG is an USB 2.0 Hi-Speed Hub Controller for embedded USB solutions. The B indicates battery charging support. The SMSC hub supports low speed, full-speed and hi-speed (if operating as a high speed hub) downstream devices on all of the enabled downstream ports. The hub provides downstream ports for embedded USB solutions and is fully compliant with the USB 2.0 Specification. Each of the SMSC hub controllers can attach to an upstream port as a full-speed or full-/hi-speed hub. The hub can support low-speed, full-speed and hi-speed downstream devices when operating as a hi-speed hub. All required resistors on the USB ports are integrated into the hub. This includes all series termination resistors and all required pull-down and pull-up resistors on D+ and D- pins. The over-current sense inputs for the downstream facing ports have internal pull-up resistors.
