Polarity of current:
The direction of current flowing into the IC is considered positive(+).
The direction of current flowing out of the IC is considered negative(-).
The voltage impressed on the open collector output terminal should be the absolute maximum voltage of the power supply.
The voltage difference between the negative terminal of the battery and the GND terminal should be 0V~0.6V.
