DESCRIPTION
The TMP300 is a low-power, resistor-programmable,
digital output temperature switch. It allows a threshold
point to be set by adding an external resistor. Two
levels of hysteresis are available. The TMP300 has a
VTEMP analog output that can be used as a testing
point or in temperature-compensation loops.
The TMP300 detects temperature with ±4°C accuracy
(max) over –40°C to +125°C.
With a supply voltage as low as 1.8V and low current
consumption, the TMP300 is ideal for power-sensitive
systems.
Available in two micropackages that have proven
thermal characteristics, this part gives a complete and
simple solution for users who need simple and
reliable thermal management.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

(1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may
degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond
those specified is not supported.
(2) Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.5V beyond the supply rails should
be current limited to 10mA or less.
(3) Short-circuit to ground.
