TUSB2036VF

The TUSB2036VF is a 3-port Hub that provides up to three downstream ports in compliance with the USB 2.0 specification. Because this device is implemented with a digital state machine instead of a microcontroller, no firmware programming is required. Fully-compliant USB transceivers are integrated into the ASIC for all upstream and downstream ports. The downstream ports support both full-speed and low-speed devices by automatically setting the slew rate according to the speed of the device attached to the ports. The configuration of the BUSPWR pin selects either the bus-powered or the self-powered mode. The introduction of the DP0 pull-up resistor disable pin, DP0PUR, makes it much easier to implement an onboard bus/self-power dynamic-switching circuitry. With the new function pin, the end-equipment vendor can reduce the total board cost while adding additional product value. The TUSB2036 supports both bus-powered and self-powered modes.
