DescriptionThe CAN-transceiver TLE6250 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, 12V and 24V systems.
Note:
There are two versions available: one for 5V logic and the other one for 3.3V logic
requiring additional supply via the V33V pin. The IC can be set to stand-by mode via an
control input. In addition the 5V-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 TLE6250 is designed to withstand the severe conditions of
automotive applications and provides excellent EMC performance.

Application Information
Figure4Mode State DiagramBoth, the TLE6250G as well as the TLE6250C offer three different operation modes
(see Figure
4), controlled by the INH and RM pin for the TLE6250 and only by the INHpin 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 TLE6250GV33 and TLE6250CV33 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 TLE6250 in normal mode.
Application Information for the 3.3V VersionThe TLE 6250V33 can be used for both; 3.3V and 5V microcontroller logic supply as
shown below. Don´t apply external resistors between the power supply and this pin. This
may cause a voltage drop and so reduce the available voltage at this pin.
