The LTM2884 USB μModule isolator combines USB data communications and USB power, and guards against ground-to-ground differentials and large common mode transients. It separates grounds by isolating a pair of USB signal transceivers using internal inductive signal isolation, providing 2.5 kVRMS isolation plus superior common mode transient rejection of >30 kV/µs. Other features include an integrated, low-EMI external- or bus-powered dc/dc converter that powers the isolated transceiver and provides up to 2.5W of isolated power for USB peripherals or hub/host controllers. The LTM2884 is available in a 15mm x 15mm x 5mm surface mount BGA package. Pricing starts at $17.35 each/1,000. For more info, visit http://www.linear.com/isolator
