Positive Supply Voltage. Connect a 0.1µF bypass capacitor from
this pin to analog VSS/GND.

VIN
External UVLO Trip Threshold Set Pin. When this pin is set to
VSS, the internal preset 0.78V UVLO trip threshold controls the
comparator output. When the applied voltage to this pin is higher
than 90mV, the SET pin sets the trip threshold and controls the
comparator output. If the SET pin is not used, connect the pin to
to VSS.

Latch Enable Pin. When ꢀꢁꢂET is set HIGH, the outputs of the
comparator will toggle normally based on the inputs to the
comparator. When ꢀꢁꢂET is set LOW and COUTPP is HIGH,
COUTPP will remain HIGH despite any changes to the input of
the comparator. COUTPP will once again respond to changes to
the input when ꢀꢁꢂET is toggled HIGH. If COUTPP is initially
LOW and the ꢀꢁꢂET is then LOW, COUTPP will stay LOW. If a
LOW-to-HIGH transition occurs on COUTPP, COUTPP will
switch to HIGH and stay HIGH and not respond to any changes
at the input. The ꢀꢁꢂET pin must always be set to a known state.
For unlatched comparator operation, set ꢀꢁꢂET to HIGH. The
open-drain output (COUTOD) is the inverted version of the
COUTPP output.
