To set the TMP300 to trip at a preset value, calculate

systems. The TMP300 uses a set resistor to program
the trip temperature of the digital output. An additional
high-impedance (210k Ω ) analog voltage output
provides the temperature reading.

voltage. The value of the
set resistor is determined by the analog output
function and the 3 μ A internal bias current.
The analog voltage output can also serve as a
voltage input that forces a trip of the digital output to
simulate a thermal event. This simulation facilitates
easy system design and test of thermal safety
circuits, as shown in Figure 8 .
