A metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) is a field-effect transistor (FET with an insulated gate) where the voltage determines the conductivity of the device. It is used for switching or amplifying signals. The ability to change...
A gate driver IC is normally used when the controller section is unable to provide sufficient current to drive the MOSFET’s gate capacitance. Sometimes, even if you use a logic level MOSFET, you might still need a driver to...
Using this fan speed controller circuit you can control the speed of 12V DC fans used in cars. The circuit is built around timer 555, which is wired as an astable multivibrator. Fan speed controller circuit Circuit operation The output of the...
ROHM has recently announced the development of a DC/DC converter IC featuring very low ON time. This enables direct step-down conversion to 3.3V or 5V from the input voltage range which includes 48V used in the automotive and industrial sectors. This step-down ratio...
A basic introduction to the Field Effect Transistor (FET). This includes a basic description of the Junction FET (JFET) and the Metal Oxide FET (MOSFET), and also discusses N-Channel vs. P-Channel, as well as Depletion Mode and Enhancement Mode...
MOSFETs are the most common transistors used today. They are switches that can be used an Arduino, BeagleBone, or Raspberry Pi. When it comes down to it, MOSFETs are pretty complicated devices. This video will cover the basics of...
FM transmissions can be received within a range of 40 km. If you are in fringe areas, you may get a very weak signal. FM DXing refers to hearing distant stations (1500 km or more) on the FM band...
