Thermal switch circuit
CIRCUIT060082
Overview
This thermal switch solution will signal low (to a GPIO pin) when a certain temperature is exceeded thus alerting when conditions are no longer optimal or device-safe. This circuit incorporates an NTC thermistor with a comparator configured in a non-inverting fashion.
Features
- Temperature switching point: Tsp = 100°C
- Output:
- Vo = HIGH: T_a < T_sp
- Vo = LOW: T_a > T_sp
- Supply:
- Vcc = 5 V
- Vee = 0 V
- V_pu = 3.3 V
