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 5000 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) package and a smaller
SSOP-16 (16-DWX) package.
