3 Description

ISOUSB111 is a galvanically-isolated USB 2.0

compliant repeater supporting low speed (1.5 Mbps)

and full speed (12 Mbps) signaling rates. The

device supports automatic connect and speed

detection, reflection of pull-ups/pull-downs, and link

power management allowing drop-in USB hub, host,

peripheral and cable isolation. The device also

supports automatic role reversal - if after disconnect,

a new connect is detected on the Upstream facing

port, then the Upstream and Downstream port

definitions are reversed. This feature enables the

device to support USB On-The-Go (OTG) and Type-C

Dual Role Port (DRP) implementations. This device

uses a silicon dioxide (SiO2) insulation barrier with a

withstand voltage of up to 5700 VRMS and a working

voltage of 1500 VRMS. Used in conjunction with

isolated power supplies, the device protects against

high voltage, and prevents noise currents from the

bus from entering the local ground. The ISOUSB111

device is available for both basic and reinforced

isolation (see Reinforced and Basic Isolation Options).

It supports a wide ambient temperature range of

–40°C to +125°C. The device is available in the

standard SOIC-16 (16-DW) packageand a smaller

SSOP-16 (16-DWX) package.
