TLE6250
Data Sheet 9 Rev. 3.9, 2007-08-22
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 (to check the bus connections
between the nodes) 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.
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 TLE6250G in normal mode.
Application Information for the 3.3 V Versions
The TLE6250GV33 can be used for both; 3.3 V and 5 V microcontroller logic supply, as
shown in Figure 6. 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.
