TI TUSB2046BIRHBT

USB集线器控制器USB3V ~ 3.6V

Overview

The TUSB2046x is a 3.3-V CMOS hub device that provides one upstream port and fourdownstream ports in compliance with the Universal Serial Bus (USB) specification as a full-speedhub. Because this device is implemented with a digital state machine instead of a microcontroller,no firmwareprogramming is required. Fully compliant USB transceivers are integrated into the ASIC forall upstream and downstream ports. The downstream ports support full-speed and low-speed devices byautomatically setting the slew rate according to the speed of the device attached to the ports. Theconfiguration of the BUSPWR pin selects either the bus-powered or the self-powered mode.
