ROHM recently announced the development of the BU6904GF/NUX and BU6906GF/NUX fan motor drivers with built-in Hall element ideal for driving cooling fans in notebook PCs, tablets, and gaming systems.

Recently, [Solder Hub] put together a brief video that demonstrates the basics of a Hall Effect sensor — in this case, one salvaged from an old CPU fan. Two LEDs, a 100 ohm resistor, and a 3.7 volt ...

Techniquesused for electrical current sensing are determined by the nature of theapplication. If current needs to be measured directly from the power mains orfrom a high-voltage dc power supply, as ...

Hall effect sensors are everywhere right now. Keyboards, game controllers, and DIY kits use them for more precise inputs. But with any newly popular device, it can be easy to immediately jump onto the ...
