Bottom Drive Outputs are held in a low state. Each of the
comparators contain hysteresis to prevent oscillations when
crossing their respective thresholds.

The NPN circuit is recommended for powering Hall or opto sensors,
where the output voltage temperature coefficient is not critical. The PNP
circuit is slightly more complex, but also more accurate. Neither circuit
has current limiting.
