Output voltage drop after using mosfet
Hi,
I am making a little smoke device for the train,
and using e-cig atomizer and AVR in project.
Since the heater require 0.6A to run, mosfet IRF3205 is added for a switch and
prevent burning the AVR.
The power supply is 3.7V li-ion battery.
When Heater directly collect to power source, it performs very well.
* V= 3.6V I= 0.67A
However, after adding a mosfet ,
it only received :
V= 1.9V I= 0.35A
It drop in a half of value..
How can I increase the output voltage even using mosfet??
