SX8000EV126 Evaluation Kit for SX8733/43/44 digital temperature sensors
GENERAL DESCRIPTION
The SX8000EV126 is an evaluation tool for the SX8733,
SX8743, SX8744 digital temperature sensors.
The SX8733, SX8743 and SX8744 are digital temperature
sensors with a 2-wire SMBus/I2C interface. It provides a
low cost solution to monitor the temperature of remote
diodes as well as its own temperature with an on-chip PN
junction sensor.
Depending on the device version, 2, 3 or 4 programmable
ports are included. They offer the possibility to trig under- /
over- temperature alarms which can be used as an interrupt
or to connect up to 3 external sensors in single-ended
mode or 2 external sensors in differential mode. The
parasitic resistances in series with the temperature
monitoring diode can be cancelled by an algorithmic, a 3point or a Kelvin (4-wire) method.
The SX8744 is pin-to-pin compatible with the LM86 part.
The SX8733 (2 programmable ports) is available in MLPDRevision 1.0 / May 2010

6 package. The SX8743 (4 programmable ports) and
SX8744 (3 programmable ports) are available in MSOP-8
package.

1. Evaluation board overview
The evaluation board is shown on Figure 1.1 and each zone is described in the corresponing subsection.
1.1. USB and external voltage
S1 is the switch to turns on and off the board. When the board is switched on, the red LED D1 is lighted.
W1 is the jumper to select the power supply from the USB or from an external source.
When the power supply from the USB is selected, the device supply voltage is 3V.
When the power supply from an external source is selected, the external voltage should be connected to P3 and be in the
range from 2.7V to 5.5V.
W2 is a jumper to remove to allows device current measurement otherwise it should be set in place.

Otherwise, insert the CD into the CD-ROM drive of your computer. The installation should start automatically. If the
installation does not start launch the file “SX8000EV126SetupVx.x.exe“located at your CD ROM root directory.
This executable includes the Microsoft .NET Framework 2.0 which is installed if it is not detected on your system.
After selection of the installation directory, the GUI will launch.
Figure 1. Installation of the GUI
2.2. Connecting the board for the first time
Ensure that the jumper W1 on the EVK is set on USB.
Connect the board to your USB port and then switch-on the SX8000EV126 using the switch S1.
The USB drivers needed by the FTDI - USB to I2C converter are installed at the first kit connection to the USB port.
Wait until the drivers installations are finished.
2.3. Running the GUI
The GUI can be launch from Windows “Start Menu->Programs->SX8000EV126->SX8000EV126”.
The GUI automatically detects the board. If not, you may have to click the “Connect” button located on the GUI tabular.
On the tab Mode setting, set the device to SX8743 and set the mode to 0.
On the tab SX controls, click on the Tj and TD1 check box to enable the sensors.
Click the Regular button to start the conversions.
The temperature curves of the sensor are display on the graph.
Well done, you are ready to sense temperatures!
