3 Description
The TMP300 is a low-power, resistor-programmable,
digital output temperature switch. The device allows a
threshold point to be set by adding an external
resistor. Two levels of hysteresis are available. The
TMP300 has a V_TEMP 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 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.
