It is also possible to change from Sleep mode to Normal Operation mode by setting the EN pin to logical “High“.
This feature is useful if the external microcontroller is continuously powered, the microcontroller power-supply is
not controlled by the INH pin. The EN pin has an integrated pull-down resistor to ensure the device remains in
Sleep or Stand-By mode even if the voltage on the EN pin is floating. The EN pin has an integrated hysteresis (see
Figure
A transition from logical “High“ to logical “Low“ on the EN pin changes the operation mode from Normal Operation
mode to Sleep mode. If the TLE7259-2GE is already in Sleep mode, changing the EN from “Low“ to “High” results
into a mode change from Sleep mode to Normal Operation mode. If the device is in Stand-By mode a change from
“Low“ to “High” on the EN pin changes the mode to Normal Operation mode, as well (see
Data Sheet
