ADUM3166BRSZ-RL

Overview

The ADUM3166BRSZ-RL is a digital isolator utilizing iCoupler technology, designed for USB peripheral isolation. It supports data rates of 1.5 Mbps, 12 Mbps, and 480 Mbps with bidirectional signal transmission. The device features a single channel in a 20-SSOP package. Key electrical parameters include an insulation voltage of 3750 Vrms, a maximum propagation delay of 500 ns, and a typical common-mode transient immunity of 50 kV/µs. Operating supply voltages range from 3 V to 5.5 V, with a typical operating current of 8 mA. The component functions within an extended industrial temperature range of -55°C to +125°C.

Feature Summary

• Supports automatic detection of low-speed, full-speed, and high-speed USB connections
• Provides re-driving and retiming capabilities to eliminate input jitter
• Features ultra-low power standby modes for suspended or disconnected states
• Offers ±6000 V IEC 61000-4-2 ESD protection across the isolation barrier

Applications

• USB peripheral isolation
• USB host isolation
• USB hub isolation

Procurement Notes

Verify part authenticity through authorized Analog Devices distributors. Confirm the specific suffix matches the reel packaging requirement. Check for RoHS compliance documentation. Ensure storage conditions adhere to moisture sensitivity levels. Validate that the component meets the required safety certifications for the target application region.

Selection Notes

Select this component when bidirectional USB isolation is required for peripherals. Compare against the ADUM3165 if unidirectional isolation or different clock input configurations are needed. Consider the 20-SSOP footprint constraints. Evaluate power consumption requirements against the specified standby currents for battery-operated devices.

Part Context

This part belongs to the ADuM3166 series of RMS digital isolators. It is part of the broader iCoupler family which uses transformer-based isolation technology. The series is engineered specifically for USB 2.0 applications, providing robust signal integrity and safety compliance for high-speed data transmission across isolation barriers.

Replacement Considerations

The ADUM3165BRSZ-RL serves as a functional alternative for designs requiring unidirectional isolation. Verify pin compatibility and check if the specific clock input configuration differences between the two models align with the system architecture.
