ADUM5410BRSZ-RL7

Overview

The ADUM5410BRSZ-RL7 is a quad-channel digital isolator featuring an integrated isoPower isolated DC-to-DC converter. It utilizes iCoupler magnetic coupling technology to provide electrical isolation between circuit sections. The device supports data rates up to 150 Mb/s with a propagation delay of 7.2 ns. It offers an insulation voltage of 3750 Vrms and operates within a temperature range of -40°C to +105°C. The component is housed in a 24-lead SSOP package and draws a typical operating supply current of 11.8 mA.

Feature Summary

• Integrates a high-efficiency isolated DC-to-DC converter to eliminate the need for external isolated power supplies on the secondary side.
• Provides four independent bidirectional or unidirectional signal channels using proprietary iCoupler magnetic coupling technology.
• Delivers high common-mode transient immunity to protect against noise spikes in electrically noisy environments.

Applications

• Industrial automation systems requiring galvanic isolation for sensor interfaces
• Medical equipment needing reliable signal transmission across safety barriers
• Power electronics control circuits involving gate drive isolation

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when ordering. Confirm that the BRSZ designation matches the required SSOP-24 package width and lead form. Ensure compatibility with the intended isolation voltage requirements, as this unit provides 3750 Vrms basic isolation. Check current availability status as distribution may vary by region.

Selection Notes

Select this component when a compact solution combining four isolated logic channels with integrated isolated power is required. It is suitable for designs where board space is limited and external isolated power components would otherwise increase complexity. Consider the 150 Mbps data rate capability to ensure it meets the system's communication speed requirements.
