IFX1051SJXUMA1

Overview

The IFX1051SJXUMA1 is an industrial high-speed CAN-FD transceiver compliant with ISO 11898-2. It supports data rates up to 2 MBit/s for CAN FD frames and operates in 12 V and 24 V applications. The device features a wide common mode range for EMI immunity, low electromagnetic emission (EME), and excellent ESD robustness of 10 kV HBM. It includes a TxD time-out function with a delay of at least 4.5 ms, receive-only mode, and short circuit protection for CANH and CANL pins against ground, battery, and VCC. The component is housed in a PG-DSO-8 package.

Feature Summary

• Guaranteed loop delay symmetry to support CAN FD data frames up to 2 MBit/s
• TxD time-out function prevents bus blocking during controller lock-up or PCB shorts
• Receive-only mode allows network monitoring without transmitting signals
• Integrated overtemperature protection and short circuit proof outputs

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 including renewable power generation

Procurement Notes

Verify the ordering part number IFX1051SJXUMA1 matches the required PG-DSO-8 package variant. Confirm that the application environment does not require automotive qualification, as this product is manufactured according to ISO9001 standards rather than automotive transportation requirements. Ensure supply voltages align with the specified functional ranges for VCC and VIO.

Selection Notes

Select this transceiver for industrial HS CAN networks requiring higher bandwidth via CAN FD support. It is suitable for mixed supply networks due to low leakage current in power-down state. Use when long bus networks are present, leveraging the extended TxD time-out timing. Ensure the microcontroller interface voltage matches the VIO supply input for proper logic level adaptation.

Part Context

This component belongs to the IFX1051 family of industrial high-speed CAN-FD transceivers. The SJ suffix indicates the PG-DSO-8 package variant, distinct from the LE variant which uses a tiny PG-TSON-8 package. Both variants share identical electrical characteristics and functionality but differ in physical footprint and thermal dissipation properties.
