One of the questions that hobbyists ask over and over is how to select the value of a current limiting resistor for an LED. Usually the seat of the pants response is: “Subtract 2 V from the supply ...

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...

The most popular display system widely used in Arduino projects is the liquid crystal display (LCD). LCD displays consists primarily of two sheets of polarized glass plates with a thin layer of liquid ...

Open-collector outputs are useful for transmitting buffered digital/pulse signals to the external world when high drive is needed. In harsh operating environments like automotive systems, however, ...

Question: Could I easily and precisely limit a current to my load? Answer: Yes, there are current limiting ICs available. In some power management applications, precise current limiting is required.
