00:00You spend the whole night building a project.
00:02Finally, it's time to test it.
00:03You turn on the power and suddenly you notice smoke coming out.
00:07Yeah, something just went very wrong.
00:09This usually happens because of reverse polarity, connecting the power in the wrong way.
00:13Diodes are a popular production method due to their simplicity.
00:16But they cause a voltage drop of about 0.8 volt.
00:19This isn't a big problem with the power supply.
00:22But when it comes to using a battery in your project,
00:24it can reduce the efficiency of your project and shorten the battery life.
00:28A MOSFET can replace a diode for protection without causing a significant voltage drop.
00:33This makes it ideal for battery power projects improving efficiency and battery life.
00:38If it is a correct connection, power flows normally.
00:40If it is a wrong connection, power is blocked instantly.
00:43So even if you are powering a microcontroller, a sensor or any other circuit,
00:47one mistake won't destroy your project.
00:49One MOSFET can save your components, time and effort.
