AQ200/AQ201: Thermal Switch

Preliminary Information

The AQ200 and AQ201 are low power three terminal thermal switches. An open collector output goes low when a preset temperature (120C or 115C respectively) is exceeded. Accuracy is guaranteed at 3 degrees.

AQ265: Programmable Thermal Switch

Preliminary Information

The AQ265 is a five pin adjustable dual thermal switch. The output is open drain, turning on when either a hot or a cold limit is eceeded. The nominal -20C (cold) and +40C (hot) limits are each adjustable with a grounded resistor The trip temperatures are programmable with 3 degree accuracy.

AQ297: Programmable Thermal Switch

Preliminary Information

The AQ297 is a five pin adjustable thermal switch. A low current circuit monitors temperature and sets an open collector output goes low when the programmed temperature is exceeded. The temperature is programmed with a single resistor with 3 degree accuracy.
