ADUM1300BRW-RL

Overview

The ADUM1300BRW-RL is a triple-channel digital isolator from Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It features unidirectional signal transmission with a data rate of 1 Mb/s and an insulation voltage of 2500 Vrms. The device operates within a supply voltage range of 2.7 V to 5.5 V, drawing typical quiescent currents of 16 mA and 57 mA per side. Propagation delay is specified at 65 ns, with rise and fall times of 3 ns. It supports a pulse width of 1000 ns and functions across a temperature range of -40°C to +105°C in a 16-SOIC package.

Feature Summary

• Triple-channel unidirectional digital isolation using iCoupler magnetic coupling technology
• High insulation voltage capability of 2500 Vrms for robust circuit separation
• Low propagation delay and fast edge rates for reliable high-speed data transmission
• Wide operating temperature range suitable for industrial environments

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing safe patient isolation
• Power metering applications with high-voltage separation needs
• Inverter drives and motor control circuits

Procurement Notes

Verify the specific suffix RL indicates reel packaging when ordering. Confirm the BRW designation corresponds to the 1 Mb/s data rate variant, distinct from higher speed models. Ensure the SOIC-16 package dimensions match your PCB footprint requirements. Check RoHS compliance status if required by your manufacturing standards. Validate that the unidirectional channel configuration aligns with your system architecture before procurement.

Selection Notes

Select this component when three isolated channels are required for unidirectional signals. The 1 Mb/s data rate suits moderate-speed communication interfaces. Consider the 2500 Vrms isolation rating for safety-critical applications. The wide supply voltage range allows flexibility in power design. Evaluate the thermal performance within the specified operating temperature range for your enclosure constraints.

Part Context

This part belongs to the ADUM1300 series of triple-channel digital isolators. It shares the same core iCoupler technology as other variants but differs in data rate and packaging. The BRW suffix typically denotes the 1 Mb/s speed grade in a tube or reel format depending on the final character. It complements single and dual-channel isolators in Analog Devices' interface portfolio.

Replacement Considerations

The ADUM1300ARWZ-RL offers similar functionality but with a 1 Mb/s rate in a Z suffix package. The ADUM1300BRWZ provides the same electrical characteristics in a tube package instead of reel. Verify pinout compatibility and package dimensions when substituting between these variants.
