Over Temperature Protection
Over Temperature Protection
Safety Features Application
An over temperature protection circuit is widely used to alert the system of high temperatures. This circuit protects the system from overheating when the internal temperature exceeds a safe threshold.
Ingredients
- Any GreenPAK w/ ACMP’s
- One resistor
- One NTC thermistor
GreenPAK Diagram
Design Steps
- Set the IN+ source of ACMP2L to Pin#18 and IN- source to the desired threshold.
- Connect one node of the resistor to VDD and the second node to Pin#18.
- Connect one node of the NTC thermistor to Pin#18 and the second node to GND.
