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 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 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.
