Comparators
This section describes three comparator circuits implemented using the HA17301P, a positive input voltage
comparator, a negative input voltage comparator, and a power voltage comparator.

Figure 7 Positive Input Voltage Comparator
Vout in the circuit shown in figure 7 will be V_OH when I^– < I⁺ and V_OL when I^– > I⁺. To assure that this
circuit operates correctly, the reference voltage must be greater than V_BE.
