7.1.2.2 Non-Inverting Comparator With Hysteresis

A non-inverting comparator with hysteresis requires a two-resistor network and a voltage reference (VREF) at the inverting input, as shown in Figure 7-5,

The equivalent resistor networks when the output is high and low are shown in Figure 7-6.

When VIN is less than VREF,, the output is low. For the output to switch from low to high, VIN must rise above the VIN1 threshold. Use Equation 4 to calculate VIN1.

When VIN is greater than VREF, the output is high. For the comparator to switch back to a low state, VIN must drop below VIN2. Use Equation 5 to calculate VIN2.

Equation 5. TLV3211-Q1 TLV3212-Q1 TLV3214-Q1 TLV3221-Q1 TLV3222-Q1

The hysteresis of this circuit is the difference between VIN1 and VIN2, as shown in Equation 6.
