ADUM3160BRWZ-RL

Overview

The ADUM3160BRWZ-RL is a digital isolator utilizing iCoupler technology for USB applications. It provides 2500Vrms isolation with a data rate of 12Mbps and 25kV/µs CMTI. The device operates on 3V to 5.5V supplies, features bidirectional channels in a 16-SOIC package, and supports USB 2.0 full-speed protocols within a -40°C to 105°C temperature range.

Feature Summary

• Integrates high-speed CMOS logic with monolithic air core transformer technology for magnetic coupling isolation.
• Supports bidirectional data transmission compatible with USB 2.0 full-speed and low-speed peripherals.
• Includes internal logic for direction detection and output buffer control based on edge detection.

Applications

• Isolating upstream USB ports in microcontroller-based systems
• Connecting USB peripherals requiring galvanic isolation
• Protecting host controllers from external bus faults

Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing. Confirm the manufacturer part number matches Analog Devices Inc. specifications exactly. Ensure the component meets required isolation voltage ratings for the target application environment before integration.

Selection Notes

Select this component for designs requiring robust USB isolation with minimal external components. The integrated direction detection simplifies circuit layout compared to standard isolators. Verify supply voltage compatibility with the target system's power rails.

Part Context

This part belongs to the ADUM3160 series of USB digital isolators. It is designed to replace traditional optocouplers in USB interfaces, offering higher speed and reliability. The BRWZ designation specifies the commercial temperature range and SOIC-16 package variant.

Replacement Considerations

Check ADUM3160 variants for different packaging or temperature grades. Ensure substitute parts maintain 2500Vrms isolation and 12Mbps data rate capabilities for USB compatibility.
