The USB isolator will protect the communication interface between a host computer such as a PC and its peripherals.
For example, ADI utilizes iCoupler_Digital_Isolation_Technology to provide USB 2.0 compliant SOIC components with data rates up to 12 Mbps, resulting in EMC protection and safe isolation performance, reduced design size, shortened design time, and reduced system cost. The electrically isolated USB μModule_ transceiver integrates a USB interface with an isolated DC-DC converter, providing up to 2.5 W of isolated power and ±15 kV ESD protection. Whether for hosts, hubs, bus taps, or peripheral devices, these transparent USB digital isolators are easy to use and function properly while meeting the demanding standards required by medical and industrial applications.
