Enable

The TLS820F0 can be switched on and off by the Enable feature: Connect a HIGH level as specified below (e.g.

the battery voltage) to pin EN to enable the device; connect a LOW level as specified below (e.g. GND) to shut it

down. The enable has a built in hysteresis to avoid toggling between ON/OFF state, if signals with slow slopes are

applied to the EN input.
