Evaluation module 'plug and play' system tests and evaluates analog temperature switch

21-01-2020 | Texas Instruments | Design & Manufacture

Texas Instruments TMP392EVM Evaluation Module is a 'plug and play' system which tests and evaluates the TMP392 analog temperature switch. The evaluation module provides resistor-programmable inputs for the dual-channel switch offering both hot and warm trip settings, to guard two different over-temperature conditions or be employed as an over-temperature shutdown/warning.

The device provides two options for supply power, a USB port or external power supply. Trip tests are offered for both channels, using the on-board pushbuttons with LED indicators at the output of the TMP392, to recognise when the sensor trips. The sensor is positioned on a breakout board which can be separated from the main PCB board to enable for prototyping.

The module does not need any calibration or software programming, as the trip points are set physically with resistors which can be replaced to test at other temperature thresholds.
