LTP2884

LTP2884 is a complete in-line USB isolator solution, ideal for any application requiring ground isolation, protection from large common mode voltage variations, or protection from spikes and surges. Built with convenience in mind, this robust isolator brings comprehensive protection to a wide variety of applications without the need for any configuration or additional software. At the heart of the LTP2884 is the LTM2884, an isolated USB 2.0 compatible µModule® transceiver with isolated power and automatic USB bus speed selection. Isolator µModule technology uses coupled inductors and an isolated power transformer to provide 2500VRMS of isolation between the upstream and downstream USB interface. All accessible lines on the LTP2884 carry additional surge protection and ESD protection up to ±20kV. Uninterrupted communication is guaranteed for common mode transients greater than 30kV/µs. LTP2884 has additional features which help to ensure reliable operation.
