• 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.”

MCP8063 12V 3-Phase BLDC Sensorless Fan Controller Demonstration Board User’s Guide

To use the MCP8063 12V 3-Phase BLDC Sensorless Fan Controller Demonstration
Board, follow these steps:

1. Plug in a daughter board on its socket (see Figure 2-1).

2. To plug in a 3-phase BLDC sensorless fan, use the daughter board fan
connector. Note that the connection can be done in normal or reverse mode. If
the fan rotates in reverse mode, the connector can be flipped to rotate in normal
mode.

3. Start the MCP8063 12V 3-Phase BLDC Sensorless Fan Controller
Demonstration Board software.

4. Plug the mini-USB cable from the USB port of a computer to the MCP8063 12V
3-Phase BLDC Sensorless Fan Controller Demonstration Board connector. The
ON LED should light up.

5. If required, let the computer identify the MCP8063 12V 3-Phase BLDC
Sensorless Fan Controller Demonstration Board. The USB LED should light up
once if the USB connection is ready.

6. Restart the computer, if required.

7. Connect the power supply to the V

2.2 MCP8063 12V 3-PHASE BLDC SENSORLESS FAN CONTROLLER DEMONSTRATION BOARD SOFTWARE DESCRIPTION

The MCP8063 12V 3-Phase BLDC Sensorless Fan Controller Demonstration Board
software window contains three tabs. The first tab is for controlling and monitoring the
MCP8063 12V 3-Phase BLDC Sensorless Fan Controller Demonstration Board, the
second tab is the Measurement Settings tab and the third tab is the Measurement

Results tab.

2.2.1 Control Tab

Figure 2-2 shows the options and functions available to control and monitor the board.

Note: All functions presented in Figure 2-2 are enabled only when the MCP8063

12V 3-Phase BLDC Sensorless Fan Controller Demonstration Board is
connected to the PC via a USB connection.

FIGURE 2-2: GUI – Control Tab.

 2014 Microchip Technology Inc. DS50002248A-page 15

MCP8063 12V 3-Phase BLDC Sensorless Fan Controller Demonstration Board User’s Guide

2.2.1.1 POWER CONTROL
The Power Control group box contains the Turn On/Off VDD button which allows the

power supply of the fan driver to be enabled/disabled.
Before enabling the fan driver power, verify the input voltage level indicated for the

board. It should be between 16V to 20V. Running outside this range may work, but
stability cannot be guaranteed. The power supply part on the board is not able to
generate a voltage level above the input voltage level.

The current is monitored and the fan driver power supply will shut down if the current
goes above 2.5A.

2.2.1.2 SPEED SETTINGS
This group box allows monitoring the FG pin frequency from the fan driver in hertz. This

frequency is converted to mechanical speed (Revolutions Per Minute - RPM) by
considering the plugged fan is a 4P/6S fan (two pairs of poles). If the plugged motor
contains a different number of poles, the value can be adapted in order to display the
correct mechanical RPM.

2.2.1.3 CHART
This part allows controlling the chart described in Section 2.2.1.4 “Display Chart”.

The chart adds 10 values per second. The three buttons have the following functions:

• Start/Stop – Allows the value acquisition to start or stop

• Clear – Removes all the values added to the chart

• Auto Scale – Allows the default scaling to be restored. In Default Scaling mode,
the chart will automatically adjust the scaling to ensure the complete view of all
the added values. In addition, when selecting a part of the chart with the mouse, it
is possibl e to zoom in the selection. The mouse wheel zoom in/out is also
enabled.

2.2.1.4 DISPLAY CHART

Once enabled, the chart will display the speed curve in RPM and the measured current
curve in mA over time. The chart adds 10 values per second.

2.2.1.5 CURRENT AND SPEED INDICATOR

This part clearly shows the instant current consumption and the instant speed.

2.2.1.6 PWM PIN

The PWM Pin box provides a slide bar to set the PWM duty cycle on the fan driver PWM
pin. The gauge below indicates the PWM duty cycle currently applied by the MCP8063
12V 3-Phase BLDC Sensorless Fan Controller Demonstration Board.

2.2.1.7 FAN DRIVER POWER SUPPLY LEVEL CONTROL

The fan driver Power Supply Pin box also provides a slide bar to set the desired voltage
value for the fan driver. The gauge below indicates the instant fan driver power supply
value measured by the MCP8063 12V 3-Phase BLDC Sensorless Fan Controller
Demonstration Board.

2.2.2 Measurement Settings Tab

The Measurement Settings tab is used to check if the fan is correctly adapted to the
fan driver by testing the fan behavior in different tests, several times, under different
conditions.

Figure 2-3 sho ws the Measurement Settings tab. See the sections below for further

details.

MCP8063 12V 3-Phase BLDC Sensorless Fan Controller Demonstration Board User’s Guide

2.2.2.1 MEASUREMENT SETTINGS

The Measurement Sett ing s Group box is used to specify the measurement corners
required. Once the automatic measurement starts (see 2.2.2.5 “Measurement

Control”), all specified corners will be tested for all selected tests. The list below details

the available corner settings:

• PWM Corners Measurement – Requires the PWM Max (%), PWM Step (%) and
PWM Min (%) v alues setting. The software will start with the maximum value
entered, and will decrease the PWM by the step value until it reaches the
minimum entered PWM value.

• Power Supply level corners are similar to the PWM corners. A power supply
level corner includes all PWM corners. This means that all PWM corners are
measured for one power supply voltage level.

• Startup check duration from Power-On [s] – 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 5s.

• Waiting time between each iteration [s] – Specifies how ma ny seconds are
allocated to stop the fan between two tests. This value will depend on the fan lag.

• Number of iterations per corner – Number of iterations for one corner.

2.2.2.2 STARTUP TEST SETTINGS

When the Enable startup test box is checked, the startup measurements are enabled,
measuring ev er y corne r for thi s test . If Enable startup test is not enabled, the startup
test is skipped. The other tests will be executed if they are enabled.

2.2.2.3 PWM CHANGE

The PWM Change measurement starts up with a PWM value of 100%. After the
specified startup delay (entered in the Startup check duration from Power-On [s]
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.

In order to save time, it is possible to not stop and restart the fan, if the last PWM
change has been done successfully by checking the Do not restart if PWM change
success check box.

2.2.2.4 SPEED CURVE AND STABILITY

This measurement requires a specified number of samples in a specified condition to
check speed stability . If the Do speed curve for the whole PWM range (100% to 5%,

each 1%) and/or the Do speed curve for the whole PSM range (14V to 2V, each

0.1V) check boxes are not checked, the corners previously set are measured. For this

test, the iterations numbering will always be 1. When one of these check boxes is
checked, the software will override the specified settings.

This test will report the current average, the maximum and minimum measured speed,
the stability in % and the sigma variation.

2.2.2.5 MEASUREMENT CONTROL

This group box contains a check box and a button that allows the user to control the
test work flow:

• Stop Measuring – Starts and stops the required measuring

• Autosave at the end of the measurements – If checked, a measurement result
file will be automatically done when all the tests has been done. See

2.2.3.1 “Measurement Results” for the file location.
