ISOUSB111 Full/Low-Speed Isolated USB Repeater

Texas Instruments' galvanically-isolated repeater is available with basic and reinforced isolation options

Image of Texas Instruments' ISOUSB111 Isolated USB RepeaterTexas Instruments' 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 hubs, hosts, peripherals, and cable isolation. The device also supports automatic role reversal, where upstream and downstream port definitions are reversed if a new connection is detected on the upstream-facing port after disconnect. 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 5,000 VRMS and a working voltage of 1,500 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 repeater device is available for basic and reinforced isolation (see reinforced and basic isolation options) supporting a wide ambient temperature range of -40°C to +125°C. The device is available in the standard SOIC-16 (16-DW) package and the smaller SSOP-16 (16-DWX) package.
