7.1.2.1 Inverting Comparator With Hysteresis

The inverting comparator with hysteresis requires a three-resistor network that is referenced to the comparator supply voltage (VCC), as shown in Figure 7-3.

The equivalent resistor networks when the output is high and low are shown in Figure 7-3.

When VIN is less than VA, the output voltage is high (for simplicity, assume VO switches as high as VCC). The three network resistors can be represented as R1 || R3 in series with R2, as shown in Figure 7-4.

Equation 1 below defines the high-to-low trip voltage (VA1).

Equation 1. TLV3211 TLV3212 TLV3214 TLV3221 TLV3222

When VIN is greater than VA, the output voltage is low. In this case, the three network resistors can be presented as R2 || R3 in series with R1, as shown in Equation 2.

Use Equation 2 to define the low to high trip voltage (VA2).

Equation 3 defines the total hysteresis provided by the network.
