I’d like some feedback on the attached design. The purpose is to power a peltier chip, via the n-Channel MOSFET, but I want to make sure I don’t mess up the wiring and damage my Arduino board. Am I missing any components, maybe a diode between the + and - on the peltier chip incase it generates a current while the system is off?
Here are a few points:
- I have a 14.8V input
- IC2 is a 6V regulator, which powers the Arduino board
- The peltier chip must receive 14.8 V @ 2A - 7A (or there about)
