|
|
I'm developing a nano quadcopter using an Atmega328 microcontroller, powered at 3.3V, and very small brushed DC motors. The average current used by these motors is about 800mA @ 3.7V.
Initially, to drive them, I used an L293D motor driver but this component was quite inefficient. The current measured when the motors ran at max power was about 500mA and so the thrust was much lower then it should be.
Now, to solve this problem, I would replace that motor driver with 4 logic level MOSFETs. After a long search, I find 2SK4033 (http://www.kynix.com/Detail/968058/2SK4033.html).
Do you know if it should work? Do I have to use it in conjunction with a diode? If the answer is "yes", what about MBR360RLG?
I chose these components also because I can buy them from the same online store.[/url] |

Hi all
I want to know what should i do to control the speed of 5A 12V dc motor using IRF44n mosfets I want to drive it by a AVR atmega32 micro controller.So please guide me.
Supply voltage =12vdc
load =max 7A

Is there a data sheet for this microcontroller? |

You can check to see if there is a manual in the box you bought, or ask your seller. _________________ embedded systems |
