The USB3803C-1-GL-TR is a low-power, USB 2.0 hub controller featuring three downstream ports and an integrated bypass switch. It supports Full-Speed, High-Speed, and Low-Speed devices with MultiTRAK technology for dedicated transaction translators per port. The device includes internal 3.3V and 1.2V regulators for single-supply operation and supports external reference clocks of 12, 19.2, 26, or 38.4 MHz. It operates within a commercial temperature range of 0°C to +70°C and is housed in a 25-ball WLCS package measuring 1.95mm x 1.95mm.
Verify the component matches the Microchip Technology USB3803C-1-GL-TR part number. Confirm the datasheet revision DS00001691D aligns with the specific silicon revision required for your design. Ensure the 25-ball WLCS package dimensions are compatible with your PCB footprint and assembly capabilities.
Select this component when designing portable systems requiring multiple USB connections with strict power constraints. The integrated regulators simplify BOM by eliminating external voltage sources. Verify that the host system can support the required I2C configuration or if the default ROM settings suffice for the application.
This device belongs to the USB3803 family, which includes the USB3803C (commercial) and USB3803Ci (industrial) variants. The 'C' suffix denotes the commercial temperature range. The 'GL-TR' suffix indicates the specific package type and tape-and-reel packaging format used for automated surface-mount assembly.
The USB3803Ci serves as the industrial temperature variant replacement. Other Microchip hub controllers like the USB2512B may offer similar functionality but differ in port count or feature sets.
