ground Power ground for connecting to the power supply.

15 PGND Power

ground Power ground for connecting to the power supply, internally connected with pin 14. 16 VPS Power input Positive power supply rail. The value is 5V. Table 2. Characteristics (Tambient=25°C)

• Object temperature refers to the actual cold side temperature of the TEC, on which the target is mounted.

** Set-point temperature is the temperature desired to have on the target. *** Can be customized to any range according to the requirement. **** This TEC controller can only drive the TECs having > 1Ω impedance, which equals VMAX/IMAX.

temperature ranges, please contact us, we will configure the internal temperature network for you. be about 10kΩ at 37°C. Now, set TEMPSP pin to 1.5V, the actual set-point temperature will be about 37°C. not certain or fixed at the early design stage. Figure 5. V

ORDERING INFORMATION

We have three versions for this TEC controller, TEC5V4A-D, TEC5V4A-DA, TEC5V4A-DB, and TEC5V4A-DAH. Only Table 3. Part # Description Maximum |VTEMP − VTEMPSP | (mV) TEC5V4A-D TEMP = On @SDNG =0 ≤5 TEC5V4A-DA TEMP = On @SDNG = 0 ≤2 TEC5V4A-DAH TEMP = On @SDNG = 0 ≤0.5 WARNING: Both the surface mount and the through hole types of modules can only be soldered manually on the board by a solder iron of < 310°C (590°F), they cannot go through a reflow oven process. NOTE: The power supply may have overshoot, when happens, it may exceed the maximum allowed input voltage, 6V, of the controller and damage the controller permanently. To avoid this from happening, do the following: 1. Connect the controller solid well with the power supply before turning on the power. 2. Make sure that the power supply has sufficient output current. It is suggested that the power supply can supply 1.2 to 1.5 times the maximum current the controller requires. 3. When using a bench top power supply, set the current limit to >1.5 times higher than the maximum current the controller requires. SPECIAL NOTE If you experience a high current spike when you change TEMPSP voltage quickly by a large amount, such as > 0.1V, a capacitor of 1uF can be added between TECCRT and GND. For TEC controlle rs manufactured after Nov. 10 , 2015, there is no such a problem.
