... L6219R 3.4 Single-pulse generator The pulse generator is a monostable triggered on the positive going edge of the comparator output. The monostable output is high during the pulse time, toff , which is determined by the time components R The single pulse switches off the power feed to the motor winding, causing the winding current to decrease during toff ...
