Description

The device AQ297 is an adjustable accurate lowpower 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 AQ297 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.
