TLE 6251 G
Description
The CAN-transceiver TLE 6251 G 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 TLE 6251 G 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 TLE 6251 G 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 TLE 6251 G 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 V_BAT fail flag reports an power-on condition at the battery supply input.
The TLE 6251 G 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.
