The Go - To - Sleep command is a transition mode allowing external circuitry like a microcontroller to prepare the
ECU for the Sleep mode. The TLE6251-2G stays in the Go - To - Sleep command for the maximum time t =
after exceeding the time
possible via the Go - To - Sleep command. During the Go-To Sleep command the following functions on the
TLE6251-2G are available:
•
•
•
•
•
•
•
•
•
Setting the NSTB pin to logical “Low”, while the EN signal remains at logical “High”, activates the Go - To - Sleep
command. The Go -To - Sleep command can be entered from Normal Operation Mode, Receive - Only Mode and
from Stand - By Mode.
5.5
The Sleep Mode is a power save mode. In Sleep Mode the current consumption of the TLE6251-2G is reduced to
a minimum while the device is still able to Wake - Up by a message on the CAN bus or a local Wake - Up event
on the pin WK. Most of the functions of the TLE6251-2G are disabled:
•
•
•
•
•
•
•

There are only two ways to enter Sleep Mode:

Data Sheet
The output driver stage is disabled.
The normal receiver unit is disabled.
The low power receiver is active and monitors the CAN bus. In case of a message on the CAN bus the
TLE6251-2G sets an internal Wake - Up flag.
The local Wake - Up pin is active and can detect a local Wake - Up event.
The INH output is active and set to
Through the internal resistors
The TxD pin is disabled.
The failure diagnostic is disabled.
The under - voltage detection on all 3 power supplies
The output driver stage is disabled.
The normal receiver unit is disabled.
The low power receiver is active and monitors the CAN bus. In case of a message on the CAN bus the
TLE6251-2G changes from Sleep Mode to Stand - By Mode and sets an internal Wake - Up flag.
The local Wake - Up pin is active and in case of a signal change on the WK pin the operation mode changes to
Stand - By Mode.
The INH output is floating.
Through the internal resistors

The TxD pin is disabled
The under - voltage detection on the power supplies
