1 Overview

The TMP390EVM allows users to evaluate the performance of the TMP390 dual-trip programmable temperature switch. The EVM comes in a USB stick form factor that can plug into a USB port to supply power and begin the evaluation of the temperature switch. The hardware is as shown in Figure 1. The module is designed so all of the features, including the manual trip test and reset of both channels, are readily available for testing. Two LED indicators are illuminated when either output of the TMP390 is triggered based on the temperature trip point. The EVM also features a perforated breakout portion of the board which can be wired to test the TMP390 in either an existing system or an oven.
