MICROCHIP USB2422-I/MJ USB Interface, USB Hub Controller, USB 2.0, 3 V, 3.6 V, SQFN, 24 Pins

The USB2422-I/MJ is a 2-port USB 2.0 high-speed Hub Controller IC with two downstream ports for embedded USB solutions. The hub controller can attach to an upstream port as a high-speed and full-speed hub or as a full-speed only hub. The hub supports low-speed, full-speed and high-speed (when configured as a high-speed hub) downstream devices on the enabled downstream ports. All required resistor on the USB ports are integrated into the hub. This includes all series termination resistors on D+ and D- pins 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.

• Supports the USB battery charging specification
• Fully integrated USB termination and pull-up/pull-down resistors
• Internal regulator provides 1.2V internal core voltage
• On-chip driver for 24MHz crystal resonator or external 24MHz clock input
• ESD protection up to 6kV on all USB pins
• Supports self-powered operation
• Downstream ports as non-removable ports
• Downstream port power control and over-current detection on an individual or ganged basis
• Supports compound devices on a port-by-port basis
