Diodes Inc.has announced the introduction of a pair of all-in-one single-phase 12 V fan motor drivers for low to medium voltage brushless DC fan control in consumer, home appliance, industrial and ...

Note that there are three main types of dc fans: two-wire, three wire, and four-wire. The two-wire fan has two pins – power and ground. This fan can be controlled either by varying DC voltage or by ...

In many new designs, smaller packaging, ever-shrinking boxes, and high-power ICs can cause heat problems. Fans can minimize overheating, but unfortunately, they are prone to mechanical problems, ...

This dc motor speed-control circuit uses standard, available components; light impinging on two independent phototransistors establishes the motor's speed.
