Note the following details of the code protection feature on Microchip devices:

• Microchip products meet the specification contained in their particular Microchip Data Sheet.

• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions.

• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

• Microchip is willing to work with the customer who is concerned about the integrity of their code.

• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.”

MTD6505 3-Phase BLDC Sensorless Fan Controller Demo Board User’s Guide

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 V

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 CONTROLLER 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.

2.2.1.1 CONTROL/MONITORING

The Control/Monitoring Group box contains two buttons:

• T urn On /Off V DD button enables/disables the power supply on the V

2.2.1.3 CHART

This part of the GUI displays a chart of the MTD6505 current consumption (mA) on the V

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 V

Current field shows the instant current measure (mA). Speed field shows the instant speed measure (RPM).

Installation and Operation

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.

MTD6505 3-Phase BLDC Sensorless Fan Controller Demo Board User’s Guide

2.2.2.1.1 Measurement Settings

The Measurement Sett ing s Group box is used to specify the measurement corners

required:

• Number of iterations – for one corner

• PWM Corners Measurement – 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.

• V

corners are similar to the PWM corners. A V

corners. This means that for one V

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.

corner includes all PWM

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 V

are not checked, the corners are measured. For this test, the iterations numbering will

always be 1. When the Do every percent PWM option is enabled, the software will

override the specified settings, and the measurement will occur for every PWM; the same procedure will happen for V

, if the check box Do every 0.1[V] for V

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

Installation and Operation

2.2.2.2 MEASUREMENT RESULTS TAB

Figure 2-4 shows the Measurement Results sub-tab:

Legend:

1 = Measurement Results table

2 = Measurement Control Group box

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 R

This section explains how to define the correct KM value for a specific fan. The KM is linked to the R reduce the efficiency.

2.3.1 Operation

Follow the next steps to define the right R

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 (V

4. Compute K

EQUATION 2-1: K

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.
