8.1 Overview

The TMP302-Q1 temperature switch is optimal for ultra low-power applications that require accurate trip thresholds. A temperature switch is a device that issues an alert response when a temperature threshold is reached or exceeded. The trip thresholds are programmable to four different settings using the TRIPSET1 and TRIPSET0 pins. Table 1 lists the pin settings versus trip points.
