PIN FUNCTIONS
BATT (Pin 1): Battery Voltage to be monitored. Supply
current is also drawn from this pin. Board layout should
connect this pin to the battery(+) terminal, through a trace
that does not conduct load current.
GND (Pin 2): Ground should be connected to the battery
(–) terminal through a trace that does not conduct load
return current.
V
threshold voltage, V
supplied by a voltage source or a resistor divider.
