9.1.2.1 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 9-3.

GUID-051390A3-FC30-4EF3-995F-DA91CC47A3AA-low.gifFigure 9-3 TLV181xin an Inverting Configuration With Hysteresis

The equivalent resistor networks when the output is high and low are shown in Figure 9-3.

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 9-4.

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

Equation 1. GUID-E148074A-5149-42F5-8B96-520D4D99FFE3-low.gif

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.
