TLE6251DS

Product Summary

The TLE6251DS is a CAN-transceiver which is a monolithic integrated circuit in a PG-DSO-8 package for high speed differential mode data transmission (up to 1 Mbaud) and reception in automotive and industrial applications. It works as an interface between the CAN protocol controller and the physical bus lines compatible to ISO/DIS 11898. As a successor to the first generation of HS CAN (TLE6250), the TLE6251DS is designed to provide an excellent passive behavior when the transceiver is switched off (mixed networks, terminal 15/30 applications) and a remote wake-up capability via CAN bus in low power mode. This supports networks with partially un-powered nodes. The TLE6251DS has two operation modes, the normal and the stand-by mode. These modes can be chosen by the STB pin. If the TLE6251DS is in stand-by mode and a message on the bus is detected, the TLE6251DS changes the level at the RxD pin corresponding to the bus signal; (2)(wake-up flag). The TLE6251DS is also designed to withstand the severe conditions of automotive applications and to support 12 V and 24 V applications. The IC is based on the Smart Power Technology SPT which allows bipolar and CMOS control circuitry in accordance with DMOS power devices existing on the same monolithic circuit.
