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.

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.
