Hi,

Does anyone have a Low Voltage Detection circuit digram which I could use to automatically shut off power to nav lights (which draw power through the receiver) at a pre-determined level ?

Many thanks,

Dave

Hi,

You could simply use a MC33064 @ 4.7v , 33164 @4.3v ( or µchip equ. ) to drive a Power Mosfet in the "ground return" of your lights supply lines ...

Alain, thank you for the information. I'm not exactly sure yet what cut-off voltage I will need, but I'm guessing it will be in the region of 9v for a 3 cell 11.1 v Li-Po battery. Will what you're thinking of handle that ? I would also need a cct diagram if you have one ?

Thanks,

Dave
