5.2 Soft-Start Circuit

When the Peltier element starts up, there is a brief surge of current through the element. This problematically tripped the overcurrent protection circuit during development, but the issue was resolved by switching to a polling-based approach, rather than continuous monitoring. However, with the Peltier element, a soft-start circuit would be a good addition. The circuit could slowly start the current through the plate, preventing the surge from occurring in the first place.
