Product details

Overview

The TMP392EVM from Texas Instruments is an evaluation module designed to rapidly assess the TMP392 dual-trip, resistor-programmable temperature switch. It supports hot/warm trip point evaluation from +30°C to +124°C with ±3.0°C accuracy, features pre-populated 9.09-kΩ (hot = +60°C) and 90.9-kΩ (warm = +30°C, 5°C hysteresis) resistors, onboard manual trip test buttons, open-drain output LEDs, and a perforated breakout section for prototyping.

For engineers reviewing the TMP392EVM datasheet, TMP392EVM board layout, TMP392EVM schematic, or TMP392EVM equivalent, this module enables immediate functional validation of dual-channel thermal trip behavior, resistor-based threshold programming, USB-powered operation, manual trigger testing, and sensor isolation via mechanical breakout-without calibration or firmware.

Technical Context

The TMP392EVM implements the TMP392A2DRLR IC in a USB-stick form factor, powered via USB Type-A connector (J2) delivering +5 V, regulated to +3.3 V by TLV70033DCKR LDO. Jumper J1 selects between USB power (pins 1–2 shorted) or external supply (2.2 V to 5.5 V applied to pin 2).

It integrates dual-channel trip evaluation using on-board 0603 resistors R3 (9.09 kΩ) and R5 (90.9 kΩ), push-button manual triggers (S1/S2), open-drain outputs (OUTA/OUTB) with integrated pull-ups, and LED indicators (D3 red, D4 green). The sensor section is mechanically separable via perforated J3 header footprint for embedded thermal testing.

FAQ

What is the primary function of the TMP392EVM?

The TMP392EVM is an evaluation module for the TMP392 dual-trip temperature switch. It allows engineers to validate hot/warm trip behavior, resistor-based threshold programming, manual trigger response, and open-drain output functionality without software or calibration. The TMP392EVM includes pre-configured trip points (+60°C and +30°C), onboard LEDs, USB power, and a breakaway sensor section-making it ideal for rapid thermal event testing and prototyping.

Does the TMP392EVM require external software or firmware to operate?

No, the TMP392EVM requires no external software, firmware, or configuration tools. Trip points are set entirely by physical resistors (R3 and R5), outputs respond directly to temperature or manual button press (S1/S2), and status is indicated by LEDs (D3/D4). The TMP392EVM operates immediately upon USB connection or external power application-fully hardware-defined and self-contained.

Can the trip points on the TMP392EVM be reconfigured?

Yes. The TMP392EVM provides two additional 0603 footprints (R4 and R6) adjacent to populated R3 and R5, allowing users to solder alternate E96-series resistors to change hot and warm trip points. R3/R4 are mutually exclusive; R5/R6 are mutually exclusive. Standard 1% tolerance E96 resistors support hot trip points from +30°C to +124°C and warm trip points from +30°C to +105°C, as defined in the TMP392 device datasheet.

How is power delivered to the TMP392EVM?

The TMP392EVM accepts power via USB Type-A connector J2 (+5 V), regulated to +3.3 V by U1 (TLV70033DCKR). Jumper J1 configures power source: short pins 1–2 for USB power; remove jumper and apply +2.2 V to +5.5 V to pin 2 for external supply. Power-good status is indicated by LED D2. The TMP392EVM does not require an external power supply but supports one when the breakout section is used independently.

What mechanical features support thermal testing with the TMP392EVM?

The TMP392EVM includes a perforated separation line along J3, enabling clean removal of the sensor section containing U2 (TMP392A2DRLR), R3/R5, and all associated terminals (SETA, SETB, OUTA, OUTB, VDD, GND). This breakout board is rated for components up to +150°C and minimizes thermal mass for faster response-ideal for oven testing or integration into target systems while retaining full electrical access and LED feedback.
