TMP392EVM User's Guide
The TMP392 is an ultra-low power, dual-trip, dual-output, resistor-programmable temperature switch. This
device enables thermal protection and thermal event monitoring over a wide temperature range. The
TMP392 offers independent dual overtemperature (hot and warm) detection in the temperature range from
+30°C to +124°C with ±3.0°C trip accuracy. The Texas Instruments TMP392EVM (Evaluation Module) is
easy to use and can evaluate the performance of the TMP392 right out of the box. The EVM has prepopulated resistors corresponding to a hot and warm trip point with 5°C hysteresis, and LED indicators at
the outputs of the device. The trip test function is available through the use of onboard push buttons to
test the output of both channels. The sensor is also located on a perforated portion of the PCB that can be
separated from the main board for prototyping. The TMP392EVM does not require any calibration or
software programming, as the trip points are programmed through two resistors. This document provides
detailed information about the device operation and evaluation board features.

Overview
The TMP392EVM allows users to evaluate the performance of the TMP392 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 TMP392 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 TMP392 in either an existing system or oven.

Power Input and Regulation
Power is supplied from the USB connector, J2, with +5 V. This input can connect to the USB port of a
laptop or desktop. The evaluation board does not require an external power supply, but one may be used
if desired (such as when the breakout board is disconnected), so long as the voltage is within the
maximum rated voltage of the TMP392.
USB power is used when J1 is shorted at pins 1-2 using a jumper. This connects +5 V to the LDO (low
dropout regulator), providing a regulated output voltage of +3.3 V. If an external supply is required, then
jumper J1 can be removed and power may be connected to pin 2 of J1. If an external supply is used, the
input voltage can be from +2.2 V to +5.5 V. The input voltage can be measured at test pin TP1 (VDD).
The LED, D2, will illuminate when power is good.
3.2
Perforated Breakout Board
The EVM board is perforated along the unpopulated J3 designator to break away the sensor portion of the
board from the power and LED output for additional prototyping and testing. J3 provides connections for
the breakout board for power, inputs, and outputs. The pins located on both sides of the J3 designator are
labeled with silkscreen on the EVM, including SETA, SETB, OUTA, OUTB, VDD, and GND. All
components on the breakout board are rated up to +150°C. The EVM was not designed with hightemperature PCB material, and thus was not designed for prolonged testing at high temperature.

Dual-Channel Resistor Programmable Trip Points
The application can use standard 1.05-kΩ to 909-kΩ E96-series resistors to set the hot trip point (Channel
A) and standard 10.5-kΩ to 909-kΩ E96-series resistors warm temperature trip points (Channel B). There
are 48 available trip points in the hot trip point range and 32 available trip points corresponding to a warm
trip point and hysteresis setting. The hot trip point may be in the +30°C to +124°C range, while the warm
trip point is in the +30°C to +105°C range. These settings can be found in the TMP392 device data sheet.
On the TMP392EVM, resistors R3 and R5 are populated to set the trip points for SETA and SETB,
respectively. These are located on the same breakout board where the TMP392 is located, and are
designated as RSETA and RSETB. The resistor in the SETA programs the hot trip point, while the resistor
in the SETB programs the warm trip point and the hysteresis settings for both channels. R3 is populated
on the EVM with a 9.09-kΩ resistor, corresponding to the hot trip point at +60°C. R5 is 90.9 kΩ,
corresponding to the warm trip point at +30°C and hysteresis of 5°C. With the trip point at +30°C, the user
can immediately visualize the tripped output after opening the EVM.
Two additional footprints for 0603 resistors, R4 and R6, are available to solder different resistors and
program alternate hot and warm trip points. Remember that R3 and R4 should not be populated at the
same time, and that R5 and R6 should also not be populated at the same time. Standard resistor values in
the E96-series that have 1% tolerance should be used for best performance.
Figure 5 shows the behavior of the output using hysteresis. When the hot trip point of +60°C is reached,
OUTA is tripped and the output will remain low until the temperature drops below the hysteresis level
subtracted from the hot threshold temperature. In this case, the hysteresis is set at 5°C, so OUTA returns
high when the temperature drops to +55°C. The same goes for the lower threshold, which is set at +30°C.
When the sensor goes to +30°C, OUTB goes low and will return high when the temperature drops to
+25°C.

Manual Trip Test and Reset
Both outputs can be tripped manually by applying a logic high to the SETA and SETB inputs to evaluate
the functionality of the outputs. On the evaluation board, there are two designated push buttons—S1 and
S2—to trip OUTA and OUTB, respectively. The output LEDs for OUTA and OUTB, D3 (red) and D4
(green), will illuminate when the trip point is reached or if the output is forced by the trip test.
3.5
Open-Drain Output
Pullup resistors are located at the open-drain OUTA and OUTB outputs. TI recommends to tie the pullup
voltage to the VDD of the TMP392. If this is not possible, however, an external voltage may be used for
VDDIO that must be less than or equal to VDD + 0.3 V of the TMP392. To connect an external VDDIO,
the 0-Ω resistor at R7 may be desoldered to remove connection to VDD, then resoldered at R9 to connect
an external supply at TP5 as shown in Figure 6.

Board Layout
The PCB is a four-layer board that includes a power regulator, the TMP392 sensor, all of the necessary
auxiliary circuitry, and various test points. The portion of the board where the sensor and resistors is
located may be broken off for evaluation separately from the rest of the EVM. This breakout board was
minimized in size to reduce the thermal mass for improving the thermal response of the TMP392.
Further layout considerations in the final design using the TMP392 may be required based on the
application. Refer to Temperature Sensors: PCB Guidelines for Surface Mount Devices for design and
layout recommendations for temperature sensors. The breakout board includes resistors rated up to
150°C for high-temperature testing, as well as the decoupling capacitor C7, which is placed as close as
possible to the TMP392.
NOTE: This PCB will not withstand temperatures of 150°C for extended periods of time because it
was not manufactured with high-temperature material.

guide, other available documentation provided by TI, and any other applicable requirements and employ reasonable and
customary safeguards. Exceeding the specified performance ratings and specifications (including but not limited to input
and output voltage, current, power, and environmental ranges) for the EVM may cause personal injury or death, or
property damage. If there are questions concerning performance ratings and specifications, User should contact a TI
field representative prior to connecting interface electronics including input power and intended loads. Any loads applied
outside of the specified output range may also result in unintended and/or inaccurate operation and/or possible
permanent damage to the EVM and/or interface electronics. Please consult the EVM user guide prior to connecting any
load to the EVM output. If there is uncertainty as to the load specification, please contact a TI field representative.
During normal operation, even with the inputs and outputs kept within the specified allowable ranges, some circuit
components may have elevated case temperatures. These components include but are not limited to linear regulators,
switching transistors, pass transistors, current sense resistors, and heat sinks, which can be identified using the
information in the associated documentation. When working with the EVM, please be aware that the EVM may become
very warm.
4.3.2
EVMs are intended solely for use by technically qualified, professional electronics experts who are familiar with the
dangers and application risks associated with handling electrical mechanical components, systems, and subsystems.
User assumes all responsibility and liability for proper and safe handling and use of the EVM by User or its employees,
affiliates, contractors or designees. User assumes all responsibility and liability to ensure that any interfaces (electronic
and/or mechanical) between the EVM and any human body are designed with suitable isolation and means to safely
limit accessible leakage currents to minimize the risk of electrical shock hazard. User assumes all responsibility and
liability for any improper or unsafe handling or use of the EVM by User or its employees, affiliates, contractors or
designees.
4.4 User assumes all responsibility and liability to determine whether the EVM is subject to any applicable international, federal,
state, or local laws and regulations related to User’s handling and use of the EVM and, if applicable, User assumes all
responsibility and liability for compliance in all respects with such laws and regulations. User assumes all responsibility and
liability for proper disposal and recycling of the EVM consistent with all applicable international, federal, state, and local
requirements.
