Introduction

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

• Microchip products meet the specifications 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 the 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 is “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.

Information contained in this publication regarding device applications and the like is provided only for your convenience and may be superseded by updates.

Product Overview

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.
MTD6501C Daughter Board Footprints and Connections are represented in Figure 1-1.

The board overview is represented in Figure 1-2.

MTD6501C DAUGHTER BOARD FEATURES

• The MTD6501C Daughter Board can be used as a 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 Soft-ware 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.

Figure 1-3 shows how the software, the board and the fan interact with one another.

WHAT THE MTD6501C 12V 3-PHASE BLDC SENSORLESS FAN CONTROLLER DAUGHTER BOARD INCLUDES
Depending on the daughter board version, the MTD6501C 12V 3-Phase BLDC Sensorless Fan Controller Daughter Board includes:

• MTD6501C Daughter Board (ADM00675)
• Important Information Sheet

Installation and Operation

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 a 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.
