Enable Function

Description Enable Function

The TLE4291 can be turned on or turned off via the EN Input. With voltage levels higher than VEN,high applied to

the EN Input the device will be completely turned on. A voltage level lower than VEN,low sets the device to low

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.
