TS9002 Rev. 1.0

In this example, a 61.9k

Ω, 1% standard

value resistor is selected for R2.

5.

Calculating R3.

R3 = (R2 + R3) - R2

= 1.068M

Ω – 61.9kΩ

= 1.006M

Ω

In this example, a 1M

Ω, 1% standard value

resistor is selected for R3.

6.

Using the equations below, verify all resistor

values selected:

VOTH = (VREF + VHYS) x

R1 + R2 + R3

R1

= 5.474V

VOTH = (VREF - VHYS) x

R1 + R2 + R3

(R1+R2)

= 4.484V

Where the hysteresis voltage is given by:

VHYS = VREF x

R5

R4
