Millenium 2 Plus Questions for switching several leds

[Carlos Best]

Guys

I'm starting to clone a Sansamp Gt2

After reading some things about the circuit y decided to use bicolor leds for the 3 selector so you could go from green-amber-red acording to the simulation, mic position, etc

I tought to combine this idea with the millenium cause it's imposible for me to get a 3pdt were I live.

Analyzing the fet its just a fancy switch that connects the led to ground when its pulled down with tha output of the circuit

heres the circuit I designed.



The questions are: I am right with these supositions? Or, will it work?
The 2N7000 will be ok with the consumption of the 6 leds (in case they are all in the amber position) running trough it?

I also used one of the variants of the millenium, that grounds the input of the circuit to avoid oscilations (a must with this high gain circuit)

Cheers
Coco

The MOSFET pulls the LEDs to ground when the control line is NOT pulled down by the output of the circuit; this is the reverse of what you said.

The 2N7000 datasheet tells you the maximum current and power dissipation.

Thanks RG!

I took a peak on the datasheets and it says

2N7000
Continuous Drain Current = 0.2A

so asumming each led consumes a maximum of 30mA

30x6=180ma

It's safe ok?

The BS170 is tougher. It says 0.5A of Continuous Drain Current. mmmm
