Notes: 1. The on resistance per single MOS transistor.

2. Stipulated for the discriminator input.

3. See figure 3. See figure 4.

4. Specified as a ratio to the R1 current.

5. The speed monitor output is low when the motor is at the set speed.

6. See figure timing chart.

7. See figure 5.

8. Refer to the operation and the formula for determining the maximum cancelable noise width Tn

(figure 6).

Noise cancellation is effective only when the FG detector output is low.

9. Design guide only.
