Changing the mode of operation

6.2

Mode change by the NEN pin

When the TLE9250V is supplied with the digital voltage VIO the internal logic works and mode change by the

mode selection pin NEN is possible.

By default the NEN input pin is logical “high” due to the internal pull-up current source to VIO. Changing the

NEN input pin to logical “low” in Power-save mode triggers a mode change to Normal-operating mode (see

Figure 7). To enter Normal-operating mode the transmitter supply VCC needs to be available.

Power-save mode can be entered from Normal-operating mode and from Forced-receive-only mode by

setting the NEN pin to logical “high”. Entering Forced-receive-only mode from Power-save mode is not

possible by the NEN pin. The device remains in Power-save mode independently of the VCC supply voltage.
