Description

ISOUSB111 is a galvanically-isolated USB 2.0 compliant repeater supporting low speed (1.5Mbps) and full speed (12Mbps) 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 5000VRMS and a working voltage of 1500VRMS. 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 reinforced isolation. The device supports a wide ambient temperature range of –40°C to 125°C. The device is available in the standard SOIC-16 (16-DW) package and a smaller SSOP-16 (16-DWX) package.
