5. PWM Carrier Frequency
6. Reverse Rotation Signal
The triangular waveform generator provides a carrier frequency of f
(The triangular wave is also used to force the switch-on of low-side transistors during square-wave drive.)
This feature provides the rotational direction of the motor every 360 electrical degrees.
A Low on the REV pin indicates 180° commutation mode (with Hall effect inputs of ≥ 5 Hz).
