TLE7268LCXUMA1

Drivers, Receivers, Transceivers Overview

The TLE7268LCXUMA1 is a dual LIN transceiver designed for automotive in-vehicle networks, supporting data transmission rates up to 20 kbps. It integrates two independent single-wire LIN transceivers compliant with ISO 17987-4, LIN Specification 2.2A, and SAE J2602 standards. The device operates within a supply voltage range of 5.5 V to 18 V and features very low current consumption in Sleep mode, typically less than 10 µA when both channels are inactive. It includes integrated wake-up capability via LIN bus traffic or EN pin signals. The component provides robust protection against short circuits to VS and GND, overtemperature conditions, and undervoltage detection. It supports 3.3 V and 5 V logic levels and is available in the PG-TSON-14 package.

Drivers, Receivers, Transceivers Feature Summary

• Integrates two independent LIN transceivers within a single device for efficient space utilization.
• Supports low-power management with wake-up functionality from Sleep mode via bus activity or enable pins.
• Includes comprehensive fail-safe mechanisms such as overtemperature shutdown, undervoltage detection, and TxD time-out protection.
• Optimized for high electromagnetic compliance (EMC) with low emission levels and high immunity to interference.

Drivers, Receivers, Transceivers Applications

• Body Control Modules (BCM)
• Gateway applications
• In-vehicle network interfaces connecting microcontrollers to LIN buses

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix XUMA1 corresponds to the required tape-and-reel packaging configuration. Confirm that the PG-TSON-14 package variant matches the PCB footprint requirements, noting its compatibility with AOI processes. Ensure the automotive qualification status meets the project's reliability standards before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-channel LIN interface is required within a compact form factor. The PG-TSON-14 package offers a smaller footprint compared to the DSO-14 variant while maintaining pin compatibility with single LIN transceivers like the TLE7257. Consider the low quiescent current and wake-up capabilities if power management in sleep states is a critical design constraint.

Drivers, Receivers, Transceivers Part Context

The TLE7268LCXUMA1 belongs to the TLE7268 family of dual LIN transceivers manufactured by Infineon Technologies. It is part of the automotive-grade product line tailored for harsh environmental conditions. The 'LC' designation specifically identifies the PG-TSON-14 package type, distinguishing it from the 'SK' variant which uses the PG-DSO-14 package.

Drivers, Receivers, Transceivers Replacement Considerations

The TLE7268SKXUMA1 serves as a pin-compatible alternative using the PG-DSO-14 package. Designers may consider this replacement if a larger surface-mount footprint is acceptable or preferred for manufacturing reasons, as both variants share identical electrical characteristics and pin assignments.
