ADUM3165BRSZ

Overview

The ADUM3165BRSZ is a single-channel digital isolator utilizing iCoupler magnetic coupling technology, designed for USB 2.0 host and peripheral isolation. It supports data rates of 1.5 Mbps, 12 Mbps, and 480 Mbps with bidirectional signal transmission. The device features a 3750 Vrms insulation voltage and operates within an extended industrial temperature range of -55°C to +125°C. Powered by 3V to 5.5V supplies, it includes low-power standby modes and offers high common-mode transient immunity of 50 kV/µs in a compact 20-SSOP package.

Feature Summary

• Supports automatic speed negotiation for Low-Speed, Full-Speed, and High-Speed USB 2.0 connections
• Provides re-driving and retiming capabilities to eliminate input jitter and ensure eye diagram opening
• Features ultra-low power standby modes for both upstream and downstream ports to meet USB suspend requirements
• Delivers robust ESD protection of ±6000V across the isolation barrier per IEC 61000-4-2 standards

Applications

• USB peripheral and host port isolation
• Industrial PC isolated USB ports for debugging or firmware upgrades
• Medical equipment and integrated PC interfaces
• Electrical test and measurement devices

Procurement Notes

Verify that the specific suffix BRSZ corresponds to the tube packaging variant rather than reel options. Confirm compliance with RoHS directives and check for any pending safety certifications such as UL 1577 or VDE requirements relevant to your region. Ensure the procurement channel provides valid traceability for the Analog Devices manufacturer identification.

Selection Notes

Select this component when designing systems requiring isolation for USB 2.0 High-Speed (480 Mbps) data links. It is suitable for applications needing flexible clock input options for either upstream or downstream ports. Consider its bidirectional nature and low standby current if power efficiency during USB suspend states is a critical design constraint.
