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.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.

Chapter 1. Product Overview
1.1
INTRODUCTION
In order to easily use the MTD6501 device, Microchip Technology provides daughter
boards for each MTD6501 device version: MTD6501D, MTD6501G and MTD6501C
daughter boards.This document covers the MTD6501C Daughter Board.
MTD6501C Daughter Board is a small board with the minimal required components to
operate with the MTD6501C device.
The MTD6501C Daughter Boards have been designed to be used with the ADM00532
motherboard, but can also be used as standalone boards using their connectors.
The MTD6501C Daughter Boards come with a kit of three boards.
Note:
In order to operate with a 3-phase BLDC motor, ensure you have direct
access to the three phases (also called U, V, W) of the motor. See
Figure 1-3.

1.2
MTD6501C DAUGHTER BOARD FEATURES
The MTD6501C Daughter Board can be used as standalone board (see
Section 2.1 “Getting Started”) but it is strongly recommended to use the MTD6501C
Daughter Board with the help of the MCP8063 12V 3-Phase BLDC Sensorless Fan
Controller Demonstration Board (ADM00532).
The MTD6501C 12V 3-Phase BLDC Sensorless Fan Controller Daughter Board allows
the control and monitoring of Microchip 12V fan driver devices, such as the MCP8063
or MTD6501. The MTD6501C 12V 3-Phase BLDC Sensorless Fan Controller Daughter
Board is controlled through PC software, via a USB connection.
The MTD6501C 12V 3-Phase BLDC Sensorless Fan Controller Daughter Boards Software provides several features, such as:
•
•
•
•
Fan driver power supply control and monitoring,
Pulse-width modulation (PWM) control,
Speed and current consumption monitoring,
Automatic application testing.
See more information about the MCP8063 kit on the Microchip website.

Chapter 2. Installation and Operation
2.1
GETTING STARTED
In Standalone mode, a power supply (2V to 14V) is required to supply the board using
the VCC and the GND connector, to operate with the daughter boards. Ensure that the
power supply can provide enough current for the application (maximum is 800 mA).
A function generator with the frequency range of 0.02 kHz to 100 kHz can be used for
the PWM pin. The PWM pin can be driven open-drain (internal pull) or logic 0V-3V. The
PWM pin can be left open in order to operate with a PWM = 100%. The FG pin allows
to read the electrical speed of the motor. The assembled R1 resistor is used as a
pull-up to VDD, so the signal will switch between 0V and 3V.
Figure 2-1 shows the connection to operate the MTD6501C Daughter Board.
