USB 2.0 - ESD & Overcurrent Protection
Solution Products
Objective
Universal Serial Bus (USB) 2.0 ports provide
up to 480 Mbps data transfer rates and 5 V
power at up to 500 mA. As a hot-pluggable
interface, it typically requires protection
against ESD and short circuits. This solution
provides this protection.
