TLE9251VLE

The Infineon TLE9251VLE is a high-speed CAN transceiver that serves as an interface between the physical bus layer and HS CAN protocol controllers. It is designed to meet the stringent requirements of automotive and industrial networks, fulfilling the ISO 11898-2 (2016) physical layer specification and SAE standards J1939 and J2284.

Key features include compliance with ISO 11898-2 (2016) and SAE J2284-4/-5, guaranteed loop delay symmetry for CAN FD data frames up to 5 MBit/s, and very low electromagnetic emission (EME) that often eliminates the need for an additional common mode choke. The device supports a VIO input for voltage adaptation to the µC interface (3.3V & 5V) and includes a Bus Wake-up Pattern (WUP) function with optimized filter time.

For enhanced reliability in automotive environments, the TLE9251VLE is qualified according to AEC-Q100. It offers excellent ESD robustness (+/-8kV HBM and +/-11kV IEC 61000-4-2), wide common mode range for electromagnetic immunity (EMI), and protection against automotive transients according to ISO 7637 and SAE J2962-2 standards. It also features CAN short circuit proofing to ground, battery, VCC, and VIO, overtemperature protection, and a TxD time-out function.

The TLE9251VLE is available in small, leadless TSON8 and PG-DSO-8 packages, both RoHS compliant and halogen-free. The TSON8 package is designed for automated optical inspection (AOI), facilitating automated assembly processes.
