Latched device shutdown. Internally the pin connects a comparator that, when the voltage
on the pin exceeds 1.85 V, shuts the IC down and brings its consumption almost to a “before
start-up” level. The information is latched and it is necessary to recycle the supply voltage of
the IC to enable it to restart: the latch is removed as the voltage on the VCC pin goes below
the UVLO threshold. Tie the pin to GND if the function is not used.
