Summary
The USB2412 is a low-power, single Transaction Translator (STT) USB 2.0 hub controller IC with two downstream ports for embedded USB applications. The USB2412 supports low-speed, full-speed, and high-speed (if operating as a Hi-Speed USB hub) downstream devices on all of the enabled downstream ports. Designed for low-power, small-footprint, mobile-oriented applications, the USB2412 is a cost-effective USB port expansion solution that requires minimal bill-of-material and configuration options. The USB2412 supports the standard commercial operating temperature range of 0° to 70°C and is designed to meet ESD protection of up to 4KV on all pins.
