I have circut, that is using a microcontroller to switch a logic level mosfet.

This mosfet is driving a load at about 500mA and 5V, but i am not sure if i can get away with just the logic level.

The datasheet states a RDs(On) max of about 50mOhm so mit Power loss would be

\[ P = I^2 * R \]

so with values: \[ 0.5^2A * 0.05 Ohm = 0.0125 W \]

Is this correct or am i missing something, because that seams rather low?

Thanks in advance for anyone who can help!

Edit: I am using the AO3400A Link to datasheet
