Figure 13. Typical Micropower Application to Set Asymmetric Positive and
Negative Hysteresis of −10 mV, +3 mV
Figure 14. Typical Micropower Application to Set Asymmetric Positive and

When V

= 0, INN = INP = V
TH
Figure 16 shows the configuration with no hysteresis when the HYSTP and HYSTN pins are connected together
to V
REF
. This configuration is not recommended because it has the highest level of false triggers due to the
system noise.
