7.2.5
The output driver stage is protected against over temperature. Exceeding the shutdown temperature results in
deactivation of the output driving stage. To avoid any toggling after the device cools down, the output driver stage
is enabled again only after a “Recessive” to “Dominant” signal change on the TxD pin (see
An Over - Temperature event only deactivates the output drive stage, the TLE6251-2G doesn’t change its
operation mode in this failure case. The Over - Temperature event is indicated by a logical “Low” signal on the
NERR pin in Receive - Only Mode.

The TLE6251-2G provides a power supply monitoring on all three power supply pins:
an under - voltage event on any of this three power supplies, the TLE6251-2G changes the operation mode and
sets an internal failure flag. The internal failure flag is not indicated by the NERR output pin.
7.3.1
An under - voltage event on the power supply
mode to Sleep Mode, regardless of the operation mode in which the TLE6251-2G might currently operate. The
logical signals on the digital input pins EN and NSTB are also disregarded. After the power supplies
have been reestablished, the operation mode can be changed by a Wake - Up event or by applying a logical “High”
signal to the EN pin or the NSTB pin.
The under - voltage monitoring on the power supply
voltage drop on each of these two power supplies is longer present as the time
operation mode change will be activated (see
