Short Description and Typical Application Diagram
The MTD415T is a compact and highly integrated temperature controller optimized for use in
high performance thermoelectric temperature control applications.
The on-chip power stage and the thermal control loop circuitry minimize external components
while maintaining high efficiency.
The output current is directly controlled to eliminate current surges. An adjustable TEC current
limit provides the highest level of TEC protection.
The MTD415T is operated from a single power supply and provides a bipolar ±1.5 A output by
connecting the TEC to the output of a bipolar power stage. True bipolar operation ensures
temperature control without “dead zones” or other nonlinearities at low TEC current values.
The digital control interface allows quick access to all system parameters as well as to digital
measurement data, this way enabling a simple integration into different systems.

Principle of Operation
In general, a temperature controller (within the blue frame) is a closed loop system. A
temperature sensor measures the temperature of the controlled object (e.g., a laser diode).
This actual temperature signal is amplified and compared with the temperature set value.
The differential signal out of the comparator controls then the current of the thermoelectric
cooler in order to maintain the temperature of the object constant. Ideally, the temperature
settling is carried out in the shortest times, with minimum settling error and without temperature
overshoots.
A thermoelectric coolers is a Peltier element that produces a temperature gradient depending
on the current direction trough the TEC. For this reason, the TEC current must be bidirectional.
In order to adapt the control loop to different thermal loads, and to optimize the temperature
controller's response characteristics, a PID amplifier is used. Closer information please see in
the PID Tutorial (page )

MTD415T
Functional Description
The MTD415T is a miniature, closed-loop temperature controller module. It is compatible with a
10 kW NTC (thermistor) temperature sensor and it's output is designed for control of
thermoelectric coolers (TEC).
The MTD415T delivers a TEC current up to 1500 mA at 4.0 V compliance voltage.
Power Supply
The supply voltage ranges from 4.5 V to 5,5 V. From the supply voltage, the internal supply
voltage for the microcontroller is derived. Further, a reference voltage for the temperature
sensor is generated (VREF; 1.8 V).
TEC Current Control
The TEC element is connected between TEC+ and TEC-. A correct connection is essential to
avoid wrong temperature correction.
The MTD415T allows to limit the maximum TEC current. Lowering the TEC current limit might
be helpful for control loop optimization in case of low thermal loads and lowers the dissipated
by the MTD415T power.
Micro-controller
The functions of the microcontroller are:
·
Comparison of the actual temperature with the set temperature;
·
Generation of the control signal for TEC output stage with respect to the comparator
signal;
·
PID loop control for optimization of the temperature settling time and for minimizing the
final temperature error.
All parameters (TEC current limit, set temperature, temperature window, PID share settings
etc.) are programmed via the UART user interface. Detailed information about how to program
the MTD415T can be found in the section Programmers Reference on page .
12
Note
The UART interface uses 3.3 V logic level. Connect the UART to a PC only using an
appropriate converter, e.g., a commercially available UART-to-USB cable.
The Status signal informs about correct operation.
The temperature control is activated by setting the Enable pin to low.

Further, with default setting of the Safety Bitmask (value = 255), the states of bits 0 to 7 are
handed over to the Status output pin - if any of the bits 0 to 7 is H, the Status level is "LOW"
and the TEC Current Output is switched off.
The Safety Bitmask can be used to mask any desired error at the Status output pin.
Attention
Masking an error may lead to damage of the MTD415T. For example, if bit 1 is masked,
exceeding the internal temperature will not be reflected on the status pin as an error and the
TEC output will not be disabled!
The safety bitmask can be programmed:
Note
If the safety bitmask should be saved for future use, it needs to be memorized using the "M"
command.

7 PID Tutorial
The general requirements to a temperature control loop are:
·
fastest settling time after power on or changing the set temperature
·
minimum residual temperature error
·
settling without temperature overshoots
·
fastest response to changes of the thermal load
PID amplifiers can fulfill these requirements. Temperature control loops are comparatively slow;
control oscillations appear with a frequency in the range of several Hz or parts of Hz. The PID
adjustment allows to optimize the dynamic behavior.
The P share is the proportional share, or the gain of the amplifier, that defines the settling time.
The higher the P share, the faster the settling and the less residual temperature error. The
downside is that high P shares lead to oscillations.
The I share is the integrating share of the amplification, or the gain at low frequencies. It allows
to minimize the residual temperature error.
Optimal settings of the P and I shares result in a fast approach to the set temperature, without
oscillations and with a minimum residual temperature error. However, such a loop is not able to
quickly react to sudden changes of the thermal load, for example, if a thermally stabilized laser
diode is set to a higher or lower output power that changes the laser's heat dissipation. The D
share (differential share, or the gain at high frequencies) allows the system to quickly react to
temperature changes, without generating oscillation of the temperature around the set point.
The MTD415T microcontroller incorporates a digital PID controller. The P, I and D shares can
be programmed manually or calculated automatically by the firmware by entering the results of
a loop oscillation test. Below an example procedure is explained in detail.
Example of a PID adjustment
Pre-conditions:
·
TEC current limit is set correctly
·
all connections are made properly
In order to observe the temperature change, connect an appropriate instrument that allows to
display the temperature change vs. time, to the TEMP input of the MTD415T.
1. Configure the PID loop:
Set temperature = 25°C: "T25000"
P share = 1000 mA/K: "P1000"
I share = 0: "I0"
D share = 0: "D0"
Cycle time = 30 ms: "C30"
2. Enable the TEC. The actual temperature Te approximates the set value.
3. Now, find the critical P share (critical gain) value at which the system starts to oscillate for a
minimum of 20 cycles without amplitude drop as a reaction to a changed set temperature.
An example procedure is described below:
·
Set P to 10.000 mA/K: "P10000".
In order to trigger loop oscillation, increase the set temperature for 0.1 K: "T25100"
·
Lower P to 5.000 mA/K: "P5000", decrease the set temperature for 0.1 K: "T25000"
and observe the loop behavior.
·
If the loop still oscillates, lower the P share again, change the set set temperature for
0.1K and observe the loop behavior.
20
MTD415T Data Sheet Rev. 1.0
© 2016 Thorlabs GmbH
Page 21
7 PID Tutorial
Example:
"P3000"; "T25100" -> the loop still oscillates
"P2000"; "T25000" -> the loop stopped oscillating
·
If the loop stopped oscillating, increase the P share, change the set set temperature for
0.1K and observe the loop behavior.
Example:
"P2500"; "T25100" -> the loop oscillates again
·
Repeat above steps.
Example:
"P2200"; "T25100" -> the loop stopped oscillating.
"P2300"; "T25000" -> the loop oscillates again
"P2250"; "T25100" -> the loop still oscillates
"P2200"; "T25000" -> the loop stopped oscillating
·
By this approximation of the P share, a value can be found at which the loop starts to
oscillate.
In our example, this happened at P = 2250 mA/K.
Read oscillation period at this value - for example, 5.58 sec.
The critical gain and the critical oscillation period are found.
4. Program the MTD415T with these values in order to trigger the calculation of the PID shares
and the cycle time by the firmware:
Program the critical gain to the found above value: "G2250"
Program the critical oscillation period: "O5580"
5. The firmware calculates the parameters of the digital PID loop and applies them instantly.
The calculated parameters can be read out using the following commands:
"P?" "[1350<LF>]" -> P share = 1350 mA/K
"I?" "[161<LF>]" -> I share = 161 mA/(K*s)
"D?" "[941<LF>]" -> D share = 941 (mA*s)/K
"C?" "[87<LF>]" -> Cycle time = 87 ms
6. Usually, at this point the PID optimization for the settling behavior is finished. If required, the
PID values and the cycle time can be manually fine tuned in order to optimize the loop
response to changes of the thermal load.
7. As a final step, save the settings to the non-volatile memory: "M"
Notes
·
The cycling time is the time base of the internal digital control loop and is calculated
automatically by entering G (critical gain) and O (critical oscillation period).
·
If manually changing the cycling time ("C"), the firmware calculates the I and the D share
anew.
·
The optimized PID parameters are valid for a steady state, that depends on the set
temperature as well as on the ambient conditions (ambient temperature, temperature of the
thermally controlled object). Any changes of the operating and/or environmental conditions
may require a re-adjustment of the PID parameters.

13 Thorlabs 'End of Life' Policy
Crossed out
"Wheelie Bin" symbol
13 Thorlabs 'End of Life' Policy
As required by the WEEE (Waste Electrical and Electronic Equipment Directive) of the
European Community and the corresponding national laws, Thorlabs GmbH offers all end
users in the EC the possibility to return “end of life” units without incurring disposal charges.
This offer is valid for Thorlabs GmbH electrical and electronic equipment
·
sold after August 13th 2005
·
marked correspondingly with the crossed out “wheelie bin” logo (see figure below)
·
sold to a company or institute within the EC
·
currently owned by a company or institute within the EC
·
still complete, not disassembled and not contaminated
As the WEEE directive applies to self contained operational electrical and electronic products,
this “end of life” take back service does not refer to other Thorlabs GmbH products, such as
·
pure OEM products, that means assemblies to be built into a unit by the user (e. g. OEM
laser driver cards)
·
components
·
mechanics and optics
·
left over parts of units disassembled by the user (PCB’s, housings etc.).
Waste treatment on your own responsibility
If you do not return an “end of life” unit to Thorlabs GmbH, you must hand it to a company
specialized in waste recovery. Do not dispose of the unit in a litter bin or at a public waste
disposal site.
WEEE Number (Germany) : DE97581288
Ecological background
It is well known that waste treatment pollutes the environment by releasing toxic products
during decomposition. The aim of the European RoHS Directive is to reduce the content of
toxic substances in electronic products in the future.
The intent of the WEEE Directive is to enforce the recycling of WEEE. A controlled recycling of
end-of-life products will thereby avoid negative impacts on the environment.
