AQ201 3ºC Accurate with Hysteresis 115ºC Thermostat SOT23, TO-92, PSOT23-6, SC70 Packages Product Specification Revision 1.3 General Description Applications The AQ201 is a simple three terminal precision low power thermostat. The temperature trip point of 115ºC is preset at the factory. The thermal hysteresis is internally programmed to 10ºC. Contact [email protected] for other trip points. • • • • The AQ201 is used to protect systems from overheating above the normal rating of components like capacitors or any other temperature sensitive component. The output OT is an open drain output that can drain up to 50mA when the threshold temperature is reached. The minimum voltage of operation is 2V. The AQ201 is offered in the thermally enhanced PSOT23-6 in order to guarantee very low thermal impedance between the heat source and the chip itself. For applications with stringent space requirements ultra small SC70 package is offered.

Absolute Maximum Ratings Stress greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These stress ratings only, and functional operation of the device at these or any conditions beyond those indicated under recommended Operating Conditions is not implied. Exposure to “Absolute Maximum Rating” for extended periods may affect device reliability. Use of standard ESD handling precautions is required.
