TD541S-44L3

Digital Isolators Overview

The TD541S-44L3 is a digital isolator from the TD541S-4xHx series manufactured by Mornsun America, LLC. It features four channels with a 5000VDC isolation voltage and supports data rates up to 150Mbps. The device utilizes capacitive coupling technology and includes an integrated isolated DC-DC converter. It operates within a supply voltage range of 3.75V to 5.25V and offers a common-mode transient immunity of 75kV/µs. The component is housed in a compact 16-BDFN package suitable for surface mount applications.

Digital Isolators Feature Summary

• Integrates an isolated DC-DC converter within a small DFN package
• Provides high-speed signal transmission at 150Mbps
• Features robust common-mode transient immunity of 75kV/µs

Digital Isolators Applications

• Industrial communication systems requiring galvanic isolation
• Medical equipment with strict isolation safety standards
• Automotive electronic control units

Digital Isolators Procurement Notes

Verify the specific suffix 'L3' against the design requirement, as it denotes the input/output configuration and voltage range distinct from other variants like 'H5'. Confirm RoHS3 compliance status and check for obsolescence notices, as some series members may be marked not recommended for new designs. Ensure the 16-BDFN footprint matches the PCB layout specifications.

Digital Isolators Selection Notes

Select this component when a compact solution with integrated power isolation is required for SPI or similar digital interfaces. The 4-channel configuration allows for parallel data transmission across isolated boundaries. Consider the 150Mbps speed limit and 75kV/µs CMTI for high-noise environments. Verify that the 3.75V-5.25V supply range aligns with the system's power architecture.

Digital Isolators Part Context

This part belongs to the TD541S-4xHx family of digital isolators with integrated power supplies. These devices are designed to replace traditional optocouplers in space-constrained applications. The family offers various channel configurations and isolation ratings, with the TD541S-44L3 specifically providing four channels in a chip-scale DFN package.

Digital Isolators Replacement Considerations

TD541S-44H3 and TD541S-44L5 are listed as parameter-equivalent alternatives from the same manufacturer.
