• Provides receive-only mode for bus monitoring without transmission
• Includes TxD time-out function to prevent bus blocking
• Offers short circuit protection against ground, battery, and VCC

Applications

• Embedded Machine Control and Factory Automation
• Building Automation systems such as HVAC and automatic doors
• Traffic Lights and Variable Message Signs (VMS)
• Elevator and Escalator applications
• Motor and Motion-Control systems including renewable power generation

Procurement Notes

Verify the specific suffix UMA1 indicates tape and reel packaging when sourcing components. Confirm that the component meets RoHS compliance requirements for your manufacturing process. Check for any obsolescence notices or end-of-life notifications from the manufacturer before finalizing procurement plans.

Selection Notes

Select this transceiver for industrial HS CAN networks requiring high bandwidth and CAN FD support. Ensure the microcontroller interface matches the VIO supply voltage capabilities. Consider the small PG-TSON-8 package size if board space is limited compared to standard DSO packages.

Part Context

This component belongs to the IFX1051 series of industrial high-speed CAN transceivers. It is designed specifically for non-automotive industrial applications where robust electromagnetic immunity and low emission are critical. The LE suffix denotes the tiny PG-TSON-8 package variant.

Replacement Considerations

The IFX1051SJ serves as the pin-compatible alternative in the PG-DSO-8 package. Verify electrical characteristics and thermal performance when substituting between package types to ensure system compatibility.
