5.1.2
The additional sense comparator provides an early warning function: Any voltage (e.g. the input voltage) can be
monitored, an undervoltage condition is indicated by setting the comparator’s output to low. See
Figure 5
The calculation of the voltage divider is easily done since the sense input current can be neglected.

The sense comparator has a hysteresis of typical 100 mV. This hysteresis of the supervised threshold is multiplied
by the resistor dividers amplification (
The sense in comparator can also be used for receiving data with a threshold of typical 1.35 V and a hysteresis
of 100 mV. Of course also the data signal can be scaled down with a resistive divider as shown above. With a
typical delay time of 4 µs receiving data of up to 100 kBaud are possible.
