Sleep Command The 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 ...

Page 13

In order to enter the Stand - By Mode or the Sleep Mode, the EN signal needs to be set to logical “Low” a defined time after the NSTB pin was set to logical “Low”. Important for the mode selection ...

Page 14

Wake - Up Functions There are several possibilities for a mode change from Sleep Mode to another operation mode. • Remote Wake - Up via a message on the CAN bus. • Local Wake - Up via a signal ...

Page 15

Local Wake - Up The TLE6251-2G can be activated from Sleep Mode by a signal change on the WK pin, also called local Wake - Up. Designed to withstand voltages up to 40V the WK pin can be directly ...

Page 16

Mode Change via the EN and NSTB pin Besides a mode change issued by a Wake - Up event, the operation mode on the TLE6251-2G can be changed by changing the signals on the EN and NSTB pins. Therefore ...
