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 TH.A (Pin 3): Threshold Adjust Pin. Adjusts the low battery
threshold voltage, V BATT.Th = 2.5V + (V TH.A /2). V TH.A can be
supplied by a voltage source or a resistor divider.
V H.A (Pin 4): Hysteresis Adjust. Hysteresis threshold
voltage V TH2 = 2.5V + (V H.A /2). V H.A can be supplied by
a voltage source or resistor divider. V H.A must always be
programmed to a higher potential than V TH.A . Hysteresis
voltage, V HYST = V TH2 – V BATT.Th .
V LOGIC (Pin 5): Positive Supply Voltage for Output Driver.
This voltage can be driven from an external logic supply
or tied to BATT.
BATTLO (Pin 6): Output of Comparator. Low for BATT
< V BATT.Th (low battery threshold voltage). Output state
guaranteed for V BATT ≥ 1.5V.
