Overview
The TLE6251DSXT is a high-speed CAN (Controller Area Network) transceiver designed by Infineon Technologies for use in automotive and industrial applications. It serves as an interface between the CAN protocol controller and the physical bus lines, ensuring compliance with ISO 11898-2 and ISO 11898-5 standards. This transceiver is built on Infineon's Smart Power Technology (SPT), which integrates bipolar and CMOS control circuitry with DMOS power devices, enhancing its performance and reliability in harsh environments.
The TLE6251DSXT is particularly suited for mixed supply CAN networks and supports data transmission rates up to 1 Mbps. It features a remote wake-up capability via the CAN bus in low power mode, making it ideal for networks with partially un-powered nodes. The device is packaged in a RoHS compliant PG-DSO-8 package, ensuring environmental sustainability and compliance with automotive standards.
