To use the MTD6505 3-Phase BLDC Sensorless Fan Controller Demonstration Board,
follow the next steps:
1. Plug in the MTD6505 plug-in module (with an MTD6505 soldered on it) on its
socket (see Figure 2-1).
2. To plug in a 3-Phase BLDC sensorless fan, choose one of these connections:
- 3-Phase fan connector from the MTD6505 3-Phase BLDC Sensorless Fan
Controller Demonstration Board (J5)
- On the MTD6505 plug-in module fan connector.
3. Connect the Power Supply to the VIN test point. VIN value is +6V ±5%. The
Power Supply should be able to deliver up to 1.0A.
4. Turn on the power switch. The POWER LED should be activated.
5. Plug the mini-USB cable from the USB port of a computer to the MTD6505
3-Phase BLDC Sensorless Fan Controller Demonstration Board connector.
6. If required, let the computer identify the MTD6505 3-Phase BLDC Sensorless
Fan Controller Demonstration Board.
7. Restart the computer, if required.
8. Start the MTD6505 3-Phase BLDC Sensorless Fan Controller Demonstration
Board Software.
Note: Once the MTD6505 3-Phase BLDC Sensorless Fan Controller
Demonstration Board Software is installed, it will automatically detect if the
MTD6505 3-Phase BLDC Sensorless Fan Controller Demonstration Board
is attached and its configuration. This means it is possible to start the
MTD6505 3-Phase BLDC Sensorless Fan Controller Demonstration Board
Software before or after enabling the board.

2.2 MTD6505 3-PHASE BLDC SENSORLESS FAN CONTROLLE R
DEMONSTRATION BOARD SOFTWARE DESCRIPTION
The MTD6505 3-Phase BLDC Sensorless Fan Controller Demonstration Board
Software window contains two tabs. The first tab is for controlling and monitoring the
MTD6505 3-Phase BLDC Sensorless Fan Controller Demonstration Board; the second
tab is the Measurement tab.
2.2.1 Controlling and Monitoring Tab
Figure 2-2 shows the options and functions available to control and monitor the board.
FIGURE 2-2: GUI - Controlling and Monitoring Tab.
All functions presented in Figure 2-2 are enabled only when the MTD6505 3-Phase

2.2.1.1 CONTROL/MONITORING
The Control/Monitoring Group box contains two buttons:
Turn On/O ff VDD button enables/disables the power supply on the VDD pin of the
MTD6505 device.
Change Direction is used to inverse the sense of the fan rotation. The Change
Direction button is available only when VDD is turned off.
2.2.1.2 RPROG PIN
The RPROG Pin Group box allows the selection of the desired RPROG resistor value.
This value depends on the KM (mV/Hz) of the fan. See the section Section 2.3 “How
to define the correct RPROG Value for more information on the RPROG selection.
One particular mode, HighZ, allows the setting of an external RPROG resistor value
directly on the plug-in module.
In order to use the MTD6502B with the MTD6505 3-Phase BLDC Sensorless Fan Con-
troller Demo Board, use KM= 0.
2.2.1.3 CHART
This part of the GUI displays a chart of the MTD6505 current consumption (mA) on the
VDD pin, and the fan speed (Revolutions Per Minute - RPM) by measuring the FG fre-
quency. The chart adds 10 values per second. The three buttons have the following
functions:
Start/Stop – allows the values acquisition to start or stop
Clear – removes all the values added to the chart
Auto Scale – allows the restoration of the default scaling. In the default scaling
mode, the chart will automatically adjust the scaling to ensure the complete view
of the whole added values. In addition, when selecting a part of the chart with the
mouse, it is possible to zoom in the selection. The mouse wheel zoom in/out is
also enabled.
2.2.1.4 PWM PIN
The PWM Group box provides a slide bar to set the PWM ratio on the MTD6505 PWM
pin. The gauge below indicates the current PWM applied.
2.2.1.5 VDD PIN
The VDD Group box also provides a slide bar to set the desired VDD value. The gauge
below indicates the instant VDD value measured by the MTD6505 3-Phase BLDC
Sensorless Fan Controller Demonstration Board.
2.2.1.6 CURRENT/SPEED FIELDS
Current field shows the instant current measure (mA). Speed field shows the instant
speed measure (RPM).

2.2.2 Measurement Tab
The Measurement tab is used to check if the fan is correctly adapted to the MTD6505
by testing the fan several times in different conditions. This tab contains two more tabs,
for settings and results.
2.2.2.1 SETTINGS TAB
Figure 2-3 shows the Setting tab.

2.2.2.1.1 Measurement Settings
The M eas ureme n t Settin gs Group box is used to specify the measurement corners
required:
Number of iterations – for one corner
PWM Corner s Measur emen t requires the PWM Max (%), PWM Step (%) and
PWM Min (%) values setting. The software will start with the maximum value
entered, and will decrease the PWM by the step value until reaches the minimum
entered PWM value.
VDD corners are similar to the PWM corners. A VDD corner includes all PWM
corners. This means that for one VDD corner, all PWM corners are measured.
Startup max delay – if the speed of the fan is measured as 0 RPM after this
delay, the startup is considered a fail. The recommended value for this field is 3s.
Inter test delay – specifies how many seconds are allocated to stop the fan
between two tests. This value will depend on the fan lag.
2.2.2.1.2 Startup
When the Startup box is checked, the startup measurements are enabled, measuring
every corner for this test. If Startup is not enabled, the Startup test is skipped. The other
tests will be executed if they are enabled.
2.2.2.1.3 PWM Change
The PWM Change Measurement starts up with a PWM value of 100%. After the
specified startup delay (entered in the Startup max delay field), the PWM changes
depending on the PWM corner specified. The software will then verify if the fan is still
running. This last check will occur after a delay value is specified in the
Braking Delay (s) field.
2.2.2.1.4 Speed Curve and Stability
This measurement requires a specified number of samples in a specified condition to
check speed stability. If the Do every percent PWM and/or Do every 0.1(V ) for VDD
are not checked, the corners are measured. For this test, the iterations numbering will
always be 1. When the Do every pe rce n t PW M option is enabled, the software will
override the specified settings, and the measurement will occur for every PWM; the
same procedure will happen for VDD, if the check box Do every 0.1[V] for VDD is
checked.
2.2.2.1.5 Measurement Control
This group box contains three buttons that allows the user to control the work flow:
Stop Measuring – starts and stops the required measuring
Clear Result – clears the current result from the screen
Save Results – stores the current measurement in an Excel file

2.2.2.2 MEASUREMENT RESULTS TAB
Figure 2-4 shows the Measurement Results sub-tab:
FIGURE 2-4: GUI - Measurement – Results Tab.
The results are stored in this table. All the tests have the first six columns in common,
with the other columns being significant only for a specific test. Settings’ control buttons
are also visible in this tab (see description in Section 2.2.2.1.5 “Measurement
Control”).

2.3 HOW TO DEFINE THE CORRECT RPROG VALUE
This section explains how to define the correct KM value for a specific fan. The KM is
linked to the RPROG (see Ta b le 2 - 1 ). An incorrect KM selection can create issues, or
reduce the efficiency.
2.3.1 Operation
Follow the next steps to define the right RPROG value:
1. Apply a constant stream of air to a fan that is not connected.
2. Using an oscilloscope, measure the waveform between two phases, when the
fan is rotating.
3. Measure the generated peak-to-peak voltage (Vp-p) value and the frequency (f).
4. Compute KM based on the measured Vp-p and f (in mV/Hz):
EQUATION 2-1: KM COMPUTE
KM should be constant, for all fan rotation speeds, but for the KM measurement, the fan
rotation speed due to the air stream, should be close to the nominal fan rotation speed.
Ta b l e 2 - 1 shows the corresponding KM for different RPROG values.
