Usage of EN/INUVLO pin in different applications
The pin EN/INUVLO is a double function pin and can be used to put the device into a low current consumption
mode. An undervoltage threshold should be fixed by placing an external resistor divider (A) in order to avoid low
voltage operating conditions. This pin can be driven by a µC-port as shown in (B) .
