TD541SCANFD

Overview

The TD541SCANFD is a chip-level isolated CAN transceiver manufactured by Mornsun, designed for industrial applications. It features an ultra-small DFN package and integrates a high-efficiency 5V isolation power supply. The device supports I/O voltages of 3.3V and 5V, operates at data rates up to 5Mbps, and provides a common-mode transient immunity (CMTI) exceeding 25kV/μs. It offers robust protection with ±58V bus fault tolerance and 15kV HBM ESD protection. The component complies with ISO11898-2 standards, supports up to 110 nodes on the bus, and functions within an industrial temperature range of -40°C to +125°C.

Feature Summary

• Integrates a high-efficiency 5V isolation power supply within a compact DFN package
• Provides superior signal integrity with CMTI greater than 25kV/μs and low loop delay
• Ensures system reliability through ±58V bus fault protection and 15kV HBM ESD resistance

Applications

• Industrial automation, control, sensor, and drive systems
• Building and greenhouse environmental control (HVAC) automation
• Security systems

Procurement Notes

Verify that the specific order matches the TD541SCANFD model designation to ensure correct isolation voltage and CAN protocol compliance. Confirm package type and pinout compatibility during integration. Check for any recent certification status updates from the manufacturer regarding UL or other safety approvals before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring high-speed CAN communication up to 5Mbps with integrated isolation power. It is suitable for environments demanding high transient immunity and wide operating temperatures. Ensure the design accommodates the DFN package dimensions and thermal requirements for the specified industrial temperature range.

Part Context

This part belongs to Mornsun's TD541 series of isolated interface components. Unlike the half-duplex RS485 variants in the same family, the TD541SCANFD is specifically engineered for full-duplex CAN bus networks. It shares the series' characteristic of integrating isolation power to simplify board layout and reduce external component count.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify electrical parameters such as CMTI, bus fault voltage, and data rate against potential alternatives to ensure functional equivalence.
