Attached schematic of a minimal USB hub, we want to embed in our product.

The only function that we require is splitting 1 USB host into 2 clients. No support of chrging is required, and only one client needs to be powered by the USB 5V.

Please let me know if this design is O.K, before I send it to layout.

Hi Eli,

The design looks functional. I do have some concerns, however, about the noise on the power rails due to the lack of decoupling and bulk capacitance. Also, the application would not be able to receive a USB Compliance logo due to non-standard connectors, no overcurrent reporting and the reported configuration options are not implemented (full power management).

Regards,
JMMN
