7.1
The TLE4291 can be turned on or turned off via the EN Input. With voltage levels higher than
the EN Input the device will be completely turned on. A voltage level lower than
quiescent current mode. In this condition the device is turned off and is not functional. The Enable Input has an
build in hysteresis to avoid toggling between ON/OFF state, if signals with slow slope are applied to the input.
