*Output voltage equals +VIN minus dropout voltage, which varies with output current. Current limits at a maximum of

1000 mA (typical).

**Select R1 so that the comparator input voltage is 1.23V at the output voltage which corresponds to the desired fault

current value.

*Connect to Logic or

μP control inputs.

LOW BATT flag warns the user that the battery has discharged down to about 5.8V, giving the user time to recharge

the battery or power-down some hardware with high power requirements. The output is still in regulation at this time.

OUT OF REGULATION flag indicates when the battery is almost completely discharged, and can be used to initiate a

power-down sequence.
