Circuits & Schematics Philips

In 1971, Signetics later Philips introduced the NE555 timer, and manufacturers are still producing more than 1 billion of them a year. By adding a few components to the NE555, you can build a simple voltage-to-frequency converter for less than 50 ...

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 without fear of destructive short-circuit ...
