IFX1054GXUMA1

Overview

The IFX1054GXUMA1 is a fault-tolerant low-speed CAN transceiver designed for industrial applications. It supports data transmission rates up to 125 kBaud and operates with a logic supply voltage (VCC) of 4.75 V to 5.25 V and a battery supply voltage (VS) ranging from 6 V to 27 V. The device features multiple low-power modes, including Sleep mode and VBAT Stand-By mode, to minimize current consumption when no data is transferred. It includes an integrated receive-only mode and optimized electromagnetic compatibility through limited and symmetric dynamic slopes on the CANL and CANH signals.

Feature Summary

• Automatic switching to single-wire mode upon detection of bus wiring failures to maintain communication
• Dual edge sensitive wake-up input pin supporting wake-up via CAN-bus or WK input
• Extended bus failure management ensuring safe operation during all bus line failure events
• Thermal protection that disables transmitter output stages if junction temperature exceeds maximum limits

Applications

• Industrial applications requiring low-speed data transmission
• Automotive electronic control units (ECUs)
• Robotics and automated guided vehicles (AGV)

Procurement Notes

Verify component authenticity by checking markings against official datasheet specifications. Confirm package type PG-DSO-14 and marking code IFX1054G. Ensure compliance with RoHS standards as indicated in the documentation. Cross-reference ordering suffixes with manufacturer resources to confirm specific packaging variants.

Selection Notes

Select this transceiver for systems requiring fault tolerance in low-speed CAN networks. Consider the extended bus failure management capabilities for harsh environments. Evaluate power consumption requirements across Normal, Receive-Only, VBAT Stand-By, and Sleep modes. Ensure supply voltages align with the specified functional ranges for VCC and VS.

Part Context

The IFX1054G belongs to Infineon's family of fault-tolerant low-speed CAN transceivers. It serves as the interface between the CAN protocol controller and physical CAN bus lines. The device is optimized for industrial use cases where reliability during bus failures is critical. It supports one-wire transmission mode with ground offset voltages up to 1.5 V.

FAQ

How does the IFX1054G handle bus line failures?

The device detects bus failures and automatically switches to a dedicated single-wire mode (CANH or CANL) to maintain data transmission. It disables the defective bus wire by switching off the affected bus termination and respective output stage.

What are the available low-power operation modes?

The IFX1054G offers Sleep mode for lowest power consumption and VBAT Stand-By mode. In Sleep mode, the external voltage regulator can be deactivated via the INH output. Wake-up requests are reported via RxD and NERR outputs.

What is the function of the INH output pin?

The INH pin is an inhibit output used for controlling an external voltage regulator. In Sleep mode, it switches to high impedance to deactivate the regulator, minimizing overall ECU current consumption.
