USB2422-I/MJ Datasheet PDF - Microchip

●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

●ESD sensitive device, take proper precaution while handling the device.
