Calculation of current monitor circuit components
Budget: $30 – $250 USD
I have the attached schematic to have a reading of current and short circuit.
The operational U6 reads current from 0 to 4A and gives a voltage variable from 0 to 3.9V.
Voltage over 3.9V is a short circuit.
The operational U4 gives high level (5V) when reads current over 50mA.
This schematic is working to give range 0 to 5V.
Now I need to calculate value of components to have a range 0-3.3V.
Important is not change U6, U4.
