Many applications using miniature brushed DC motors require motors to operate at more than one load point or through specific load cycles. Running a motor at usable load points requires a variable, ...
A recent Design Idea, “Three discretes suffice to interface PWM to switching regulators,” demonstrated one way to use PWM to control the output of a typical switching voltage regulator. There were ...
This Design Idea describes a circuit employing a small microcontroller-based sensor module with only three connections: 5V dc, an RS-232 transmit-data output, and ground. A dedicated single-voltage ...
