Hi, I have a question about a setup im having problems with.
Here is the setup I have a bfb1012hh blower connected to the Atmega328. From pin5 to a 1k resistor>Irl501>22uf>12v>1n4001>Blower. The link is a pic of the scemantic used. http://imageshack.us/photo/my-images/59/blower.png/
the picture does not show the 1k resistor between the AtMega328 and the IRL501
The problem is that im using a bigger blower then what was suppost to have. The Atmega will lockup and needs to be reset, I believe when the is turning on or off and also when the IRL501 gets hot, which means I could probably add a heatsink to it and that could solve my problem.
But, I would like to know the solution. Would there be a better setup to do this. It works just fine with a smaller 6.7cfm 12v blower. but the 1012hh is a 34cfm max blower. From another forum someone said maybe adding a transistor before the mosfet, but he had not done that before and was not sure about how to go about doing so
Any help with this I would be very greatfull
