TD541SCANH

Overview

The TD541SCANH is a digital isolator manufactured by Mornsun America, LLC, designed for isolated CAN bus communication. It integrates a high-efficiency 5V power supply and supports I/O voltage ranges of 3.3V and 5V. The device features a compact DFN package and meets ISO11898-2 standards. Key electrical parameters include an isolation voltage of up to 5000VDC, a data rate of 1Mbps, and a common-mode transient immunity greater than 25kV/µs. It operates within a temperature range of -40°C to +125°C and provides bus fault protection from -40V to 40V.

Feature Summary

• Ultra-small, ultra-thin chip-level DFN packaging
• Integrated 5V high-efficiency power supply
• High bus electrostatic discharge protection up to 15kV (HBM)
• Driver dominant timeout function

Applications

• Isolated CAN transceivers in industrial automation
• Automotive electronic control units requiring robust ESD protection
• Systems needing galvanic isolation between microprocessors and CAN buses

Procurement Notes

Verify component authenticity through authorized distributors or the manufacturer directly. Confirm RoHS compliance and AEC-Q100 qualification status if automotive applications are intended. Check for any recent updates regarding UL certification validity, as previous notices indicated potential anomalies affecting certificates issued after May 2024.

Selection Notes

Select this component when a single-chip solution combining isolation and CAN transceiver functionality is required. Ensure the design accommodates the integrated 5V regulator's current requirements. Verify that the 1Mbps data rate aligns with system timing constraints and that the DFN footprint fits the PCB layout limitations.
