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 t
Output stage
The output stage contains four darlington transistors (source drivers) four saturated
transistors (sink drivers) and eight diodes, connected in two H bridge.
Figure 4.
The source transistors are used to switch the power supplied to the motor winding, thus
driving a constant current through the winding. It should be noted however, that is not
permitted to short circuit the outputs.
