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, t
timing 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 and four diodes, connected in an H-
bridge. The two sinking transistors are used to switch the power supplied to the motor
winding, thus driving a constant current through the winding.
It is not permitted to short circuit the outputs.
V
The circuit stands any order of turn-on or turn-off the supply voltages V
dV/dt values are then assumed.
Preferably, V
Analog control
The current levels can be varied continuously if VR is varied with a circuit varying the voltage
on the comparator terminal.
