TLT9251VLEXUMA1

Drivers, Receivers, Transceivers Overview

The TLT9251VLEXUMA1 is a high-speed CAN FD transceiver from Infineon Technologies, designed for automotive and industrial applications. It complies with ISO 11898-2 (2016) and supports data rates up to 5 MBit/s. The device operates within a transmitter supply voltage range of 4.5 V to 5.5 V and a digital supply voltage range of 3.0 V to 5.5 V. It features an extended junction temperature range from -40°C to +150°C and offers ESD protection of +/-8 kV (HBM). Packaged in a leadless PG-TSON-8 format, it includes features such as a bus wake-up pattern function, stand-by mode, and overtemperature protection.

• Car powertrain and transmission applications
• Gateway Modules
• Body Control Modules (BCM)
• Engine Control Unit (ECUs)

Drivers, Receivers, Transceivers Procurement Notes

Verify the component authenticity by checking the marking code 'T9251V' on the PG-TSON-8 package against official Infineon documentation. Ensure that the ordering suffix matches the specific reel or cut tape configuration required for your assembly line. Confirm RoHS compliance status through the manufacturer's certificate before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this transceiver when designing networks requiring high-speed communication up to 5 MBit/s with strict EMC constraints. It is suitable for microcontrollers operating at either 3.3 V or 5 V logic levels via the VIO pin. Consider its small footprint and AOI-compatible packaging for space-constrained PCB layouts in automotive environments.
