Enable Function

7.1

Description Enable Function

The TLE4699 can be turned on or turned off via the EN Input. With voltage levels higher than

V

the EN Input the device will be completely turned on. A voltage level lower than

V

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.
