5. Determine the component value using the following formula as a guideline:

C108 (µF) = 220

ffg (Hz)

Digital filter time TMASK of FG signal is determined as follows.

TMASK (sec) =

CLK × D2

∼

2

CLK × D2

where, CLK : The reference frequency.

D2 : CLK frequency dividing ratio.

7. The formula shown below roughly determines the time, Tprot (s), until the stuck rotor protection

circuit operates. Figure 2 shows the operating waveforms. The latched state can be cleared by

either CE or VCC. Note that a capacitor with a leakage current sufficiently smaller than the

charging current Ict+ must be used.
