ADUM3100BRZ-RL7

Overview

The ADUM3100BRZ-RL7 is a single-channel digital isolator utilizing iCoupler technology, which integrates high-speed CMOS circuitry with monolithic transformer coupling. It provides robust galvanic isolation with a rated insulation voltage of 2500 Vrms and a common-mode transient immunity (CMTI) of 25 kV/µs. The device supports data rates up to 100 Mb/s with typical propagation delays of 10.5 ns and rise/fall times of 3 ns. It operates on a supply voltage range of 3 V to 5.5 V, drawing approximately 10 mA of quiescent current per channel. Packaged in an 8-SOIC surface-mount format, it functions within an industrial temperature range of -40°C to +105°C.

Feature Summary

• Integrates high-speed CMOS logic with monolithic transformer technology for compact isolation solutions
• Provides unidirectional signal transmission with high common-mode transient immunity
• Eliminates the need for external magnetic components through on-chip transformer integration

Applications

• Industrial process control systems requiring signal isolation
• Medical equipment needing patient isolation barriers
• Power management circuits for gate drive isolation

Procurement Notes

Verify the specific suffix RL7 confirms reel packaging when sourcing. Confirm the BRZ variant meets the required 100 Mbps speed grade, as other variants exist within the ADUM3100 family. Ensure the SOIC-8 package width matches the PCB footprint design constraints. Check for RoHS compliance documentation if required by local regulations.

Selection Notes

Select this component when a single-channel, unidirectional isolator is sufficient for the application. The 100 Mbps data rate suits moderate-speed digital interfaces. Consider the 2500 Vrms isolation rating against the system's working voltage requirements. Evaluate the 8-SOIC package size against available board space compared to wider packages.

Part Context
