USB 2.0 HUB using HS8836A

Overview

I. General Introduction
My old docking station, which I bought for 3 yuan on Taobao, broke after only a few days. So I designed a new board myself, and it's been working perfectly for almost half a month now! This USB 2.0 hub, made using the HS8836A, expands the output to 4 ports and has short-circuit and electrostatic discharge (ESD) protection.

II. Function Introduction
1. Added ESD Protection

2. Added Short-Circuit Protection
A PW1502 chip is used for current limiting, and this chip also has reverse current protection. You can adjust the protection current according to your computer's needs.

3. Circuit Principle
All circuit parts are drawn according to the recommendations in the datasheet, so please read the chip datasheet in the attachment!
Besides these components and the circuit board, you should also prepare a USB cable!
III. Summary
This hub is simple to make and inexpensive, making it very practical for debugging related projects. Its short-circuit and reverse current protection functions greatly protect our electronics enthusiasts' computers. I hope this is helpful to you!
