Figure 3 illustrates the locus of operating
current and voltage for two different TECs.
Example 1:
A supply voltage of 5 Volts was chosen for
use with the ITI Ferro Tek Model
6300/018/018A TEC. This device is rated for
a maximum current of 1.8 Amperes at a
maximum allowable voltage of 2.7 Volts.
This is a load resistance of approximately
1.5 ohms. The intersection of the 1.5 ohm
load line and the HY-5610 current source
characteristic's define the locus of operation
voltage and current for both the HY-5610
and the TEC. In this application the current
was limited to 1.8 Amperes when cooling and
to 0.6 Amperes when heating by proper
selection of R
& R
.

Example 2:
A supply voltage of 12 Volts was chosen for
the Melcor FC 0.45-66-05 TEC. This device
has a maximum rated voltage of 7.98 Volts
at a current of 0.8 Amperes. A load line for
this device is also shown on the plot. Once
again maximum turn on current is set by
proper selection of R
CC
& R

Note that the power dissipated in the HY-
5610 never exceeds the 6 Watt maximum
power dissipation in both of these examples.

Figure 2 illustrates the characteristics of
the HY-5610 power drive section. It also
illustrates the unsafe operating area
where the power dissipated in the device
exceeds the maximum 6 watt rating.
This curve applies for both heating and
cooling operation.
Note that the resistance of the power
drive section is approximately one ohm
when the HY-5610 is fully turned on.
