Zetex Semiconductors have a siren driver IC Type ZSD100 available that is suitable for use in alarm systems for cars and model craft. With the addition of only a few components as shown in the diagram ...

Even robotic systems occasionally need a cooling fan. When they do, the cooling circuit must be an intelligent one that makes minimal demands on power consumption and space. The circuit described here ...

The key to obtaining the best performance on your successive-approximation-register (SAR) analog-to-digital converter (ADC) is optimizing the driver amplifier and resistor-capacitor (RC) filter ...

This simple circuit adds short-circuit load protection to a basic driver such as the output of a simple logic gate, while allowing it to control a high-power load operating at a much-higher voltage ...
