AQ297
3ºC Accurate with Hysteresis
Adjustable Thermostat
SOT23-5 Package
Product Specification
Revision 1.1
October 08, 2006
General Description
The device AQ297 is an adjustable accurate low-
power solid-state thermostat. The temperature trip
point can be set with one external resistor from 50ºC
to 150ºC with an accuracy of 3 degrees. The thermal
hysteresis is internally programmed to guarantee
stability at the transition point.
The device AQ297 is used to protect systems from
overheating above the normal rating of components like
capacitors, batteries, or any other temperature
sensitive component. The device AQ297 is also used in
battery management systems to stop the battery
charge when the battery temperature is outside of the
safe temperature range.
The output OT is an open drain output that can sink up
to 50mA when the threshold temperature is reached.
The minimum voltage of operation is 2.2 V.
Applications
Battery Chargers
Electronic System protection
Fan Control
Microprocessor Thermal Management
