Hello,

I want to implement Low Voltage Detection in PSoC 4100s CY8C4146LQI-S422 microcontroller.

I noticed there is not LVD component available and also the GlobalSignal component does not offer the options for low voltage interrupt generation.

Any idea on how I can detect a low voltage in my system? I cannot find a component to do that!

Thanks!!

Hi,

Although I have never tired by myself, the CSD_Comp seems to be a nice component for that purpose.

You can adjust the reference and if you add interrupt, may be you can implement LVD like function.
