It is also possible to change from Sleep mode to Normal operation mode by setting the EN pin to logical “Low“.This
feature is useful if the external micro controller is continuously powered and not connected to the INH pin. The EN
pin has an integrate 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
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 TLE7259G 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 (see
