9.1.1 ON and OFF Control

The EN/UVLO pin controls the state of the switch. Asserting EN/UVLO high enables the switch. EN/UVLO is active high and has a low threshold that can interface with low-voltage signals. The EN/UVLO pin is compatible with standard GPIO logic thresholds. It can be used with any microcontroller with 1.2 V or higher GPIO voltage. This pin cannot be left floating and must be driven either high or low for proper functionality.
