Suggested by Sprague in the 1980s documentation, this circuit can control three-phase AC motors. The original documentation does not specify the maximum motor current.
With this circuit it is possible to keep the current in an LED constant even if the supply voltage...
This circuit was suggested by Motorola in its manual of components for optoelectronics (1987)...
This sensitive circuit can be designed with FETs such as BF245 and MPF102. The sensor is a silicon...
