This circuit with low-slip characteristics uses an operating system that is not very common today. The circuit can be designed with more modern operational and equivalent FETs.
This circuit makes use of components from the time it was published. The TCA151 is not a common...
This circuit can be used with motors or resistive loads, such as heaters and incandescent lamps....
Short pulses can be found in this 90's EDN circuit. The load is 50 ohms and the transistors are from that...
