AQ200

AQ200 3ºC Accurate with Hysteresis 120ºC Thermostat SOT23, TO-92, PSOT23-6, SC70 Packages Product Specification Revision 1.7 November 08, 2006 General Description The AQ200 is a simple three terminal precision low power thermostat. The temperature trip point of 120ºC is preset at the factory. The thermal hysteresis is internally programmed to 10ºC. Contact sales@acutechnology.com for other trip points. The AQ200 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 AQ200 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. For applications where the thermal resistance is not critical the AQ200 can be used in the more common packages SOT23-3 or TO92.
