Description
The CAN-transceiver TLE 6250 is a monolithic integrated circuit that is available as bare
die as well as in a P-DSO-8-3 package. The IC is optimized for high speed differential
mode data transmission in automotive and industrial applications and is compatible to
ISO/DIS 11898 (see page 12 and 20). It works as an interface between the CAN protocol
controller and the physical differential bus in both, 12 V and 24 V systems.
Note:
There are two versions available: one for 5 V logic and the other one for 3.3 V logic
requiring additional supply via the V
33V
pin. The IC can be set to stand-by mode via an
control input. In addition the 5 V-version offers a receive only mode feature to support
diagnostic functions.
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. The TLE 6250 is designed to withstand the severe conditions of
automotive applications and provides excellent EMC performance.

Application Information
Figure 4
Mode State Diagram
Both, the TLE 6250 G as well as the TLE 6250 C offer three different operation modes
(see Figure 4), controlled by the INH and RM pin for the TLE6250 and only by the INH
pin for the 6250 V33. In the normal mode the device is able to receive and to transmit
messages whereas in the receive-only mode signals at the TxD input are not transmitted
to the CAN bus. The receive-only mode can be used for diagnostic purposes as well as
to prevent the bus being blocked by a faulty permanent dominant TxD input signal. The
stand-by mode is a low power mode that disables both, the receiver as well as the
transmitter. For the TLE 6250 G V33 and TLE 6250 C V33 the receive only mode
feature is not available. The inhibit feature for this versions works in the same way as for
the 5V versions.
In case the receive-only feature is not used the RM pin has to be left open. When the
stand-by mode is not used the INH pin has to be connected to ground level in order to
switch the TLE 6250 in normal mode.
