7.2.1.2 Detailed Design Procedure

First, create an equation for VT that covers both output voltages when the output is high or low.
Equation 1. TLV3604 TLV3605 TLV3607
Equation 2. TLV3604 TLV3605 TLV3607
The hysteresis voltage in this network is equal to the difference in the two threshold voltage equations.
Equation 3. TLV3604 TLV3605 TLV3607
Equation 4. TLV3604 TLV3605 TLV3607
Equation 5. TLV3604 TLV3605 TLV3607
Equation 6. TLV3604 TLV3605 TLV3607
Note that these equations do not take into account the effects of the internal hysteresis and offset voltage of the comparator. Design parameters need to be adjusted accordingly. Select a value for R2. Plug in given values for VREF, VT1, VT2, Q, and Q, and solve for R1. For the given example, R2 = 50kΩ, and R1 is solved as = 8.3kΩ.
