3. Integral constants R2, C1 and C2 can be designed as follows.
4. It is notice that rotation speed error Nerror is caused by leak current Icer2 on pin 22 and this error
5. Oscillation period t
6. The capacitor C103 on pin 39 can be determined by t
7. LVI operatig voltage Vsd1, Vsd2 and its hysteresis voltage Vhys1, Vhys2 can be determined by
R2 =
C1 =
C2 = 10 • C1
Nerror = Icer2 •
