DESCRIPTION
The TMP300B-Q1 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 TMP300B-Q1 has a VTEMP analog
output that can be used as a testing point or in
temperature-compensation loops.
With a supply voltage as low as 1.8V and low current
consumption, the TMP300B-Q1 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.
