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.
