Suggested by Motorola documentation from the 1980s, this circuit can be implemented with equivalent power MOSFETs. The type depends on the current of the controlled motor, as well as the diodes.
Using the CA3140 in the figure we have a comparator that goes low in the window voltage space. The...
With this circuit it is possible to connect a comparator to a power stage via two wires. The...
This simple circuit was found in the May 1979 issue of Radio Electronics magazine. The circuit has the...
