TLE6251G Datasheet

Network Controller & Processor ICs


The CAN-transceiver TLE6251G is a monolithic integrated circuit in a P-DSO-14-13 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, the TLE6251G is designed to provide an excellent passive behavior when the transceiver is switched off (mixed networks, clamp15/30 applications). The current consumption can be reduced, due to the low power modes.. This supports networks with partially powered down nodes. The TLE6251G offers two low power modes as well as a receive-only mode to support software diagnosis functions. A wake-up from the low power mode is possible via a message on the bus or via the bi-level sensitive wake input. An external voltage supply IC can be controlled by the inhibit output. So, the µC can be powered down and the TLE6251G still reacts to wake-up activities on the CAN bus or local wake input. A diagnosis output allows mode dependent enhanced diagnosis of bus failures and wake-up source. A VBAT fail flag reports an power-on condition at the battery supply input. The TLE6251G is 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.
