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 and not connected to 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
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 TLE7259-2GU 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
