MTD6505
3-Phase Sinusoidal Sensorless Brushless Motor Driver
Features
Description
• 180° Sinusoidal Drive for High Efficiency and Low
Acoustic Noise
The MTD6505 device is a 3-phase, full-wave
sensorless driver for brushless DC (BLDC) motors. It
features 180° sinusoidal drive, high-torque output and
silent drive. With the adaptive features, parameters and
wide range of power supplies (2V to 5.5V), the
MTD6505 is intended to cover a broad range of motor
characteristics, while requiring minimum external
components. Speed control can be achieved through
either PSM or PWM.
• Position Sensorless BLDC Drivers
(no Hall Effect Sensor required)
• Integrated Power Transistors
• Supports 2V to 5.5V Power Supplies
• Programming Resistor (RPROG) Settings to Fit
Motor Constant (KM) Range from 3.25 mV/Hz to
52 mV/Hz
The compact packaging and the minimal bill of
materials make the MTD6505 device extremely
cost-efficient in fan applications. For example, the CPU
cooling fans in notebook computers require designs
that provide low acoustic noise, low mechanical
vibration, and are highly efficient. The frequency
generator (FG) output enables precision speed control
in closed-loop applications.
• Direction Control:
- Forward direction: connect DIR pin to GND or
leave floating
- Reverse direction: connect DIR pin to VBIAS
or 3V
• Speed Control through Power Supply Modulation
(PSM) and/or Pulse-Width Modulation (PWM)
• Built-in Frequency Generator (FG Output Signal)
The MTD6505 device includes Lockup Protection mode
to turn off the output current when the motor is in a lock
condition, with an automatic recovery feature to restart
the fan when the lock condition is removed. Motor
overcurrent limitation and thermal shutdown protection
are included for safety-enhanced operations.
• Built-in Lockup Protection and Automatic
Recovery Circuit
• Built-in Overcurrent Limitation
• Built-in Thermal Shutdown Protection
• Built-in Overvoltage Protection
• No External Tuning Required
• Available Package:
The MTD6505 is available in a compact, thermally-
enhanced, 10-lead 3 mm x 3 mm UDFN package.

4.3
Frequency Generator Function
4.0
FUNCTIONAL DESCRIPTION
The Frequency Generator output (FG) is a “Hall Effect
Sensor equivalent” digital output, giving information to
an external controller about the speed and phase of the
motor. The FG pin is an open-drain output, connecting
to a logical voltage level through an external pull-up
resistor. When a lock or an out-of-sync situation is
detected by the driver, this output is set to
high-impedance until the motor is restarted. Leave the
pin open when it is not used.
The MTD6505 generates a full-wave signal to drive a
3-phase BLDC motor. High efficiency and low power
consumption are achieved due to CMOS transistors
and synchronous rectification drive type.
4.1
Speed Control
The rotational speed of the motor can be controlled
either through the PWM digital input signal or by acting
directly on the power supply (VDD). When the PWM
signal is High (or left open), the motor rotates at full
speed. When the PWM signal is low, the IC outputs are
set to high-impedance and the motor is stopped.
4.4
Lock-Up Protection and Automatic
Restart
If the motor is blocked and cannot rotate freely, a
lock-up protection circuit detects it and disables the
driver by setting its outputs to high-impedance to
prevent the motor coil from burnout. After a “waiting
time” (TWAIT), the lock-up protection is released and
normal operation resumes for a given time (TRUN). If
the motor is still blocked, a new period of waiting time
is started. TWAIT and TRUN timings are fixed internally,
so that no external capacitor is required.
By changing the PWM duty cycle, the speed can be
adjusted. Thus, the user has freedom to choose the
PWM system frequency within a wide range (from
1 kHz to 100 kHz).
Since the PWM pin has an internal pull-up resistor
connected to VDD, it is recommended to drive it
between 0V and high Z. The PWM driver must be able
to support the pull-up resistor current to drive the pin.
See “PWM Internal Pull-Up Resistor” in Section 1.0,
Electrical Characteristics.
4.5
Overcurrent Protection
The output transistor activation always occurs at a fixed
rate of 30 kHz, which is outside the range of audible
frequencies.
The motor peak current is limited by the driver to
750 mA (standard value), thus limiting the maximum
power dissipation in the coils.
Note 1: The PWM frequency has no direct effect
on the motor speed and is asynchronous
with the activation of the output transistors.
4.6
Thermal Shutdown
The MTD6505 device has a thermal protection function
which detects when the die temperature exceeds
TJ = +170°C. When this temperature is reached, the
circuit enters Thermal Shutdown mode, and outputs
OUT1, OUT2 and OUT3 are disabled (high-imped-
ance), avoiding IC destruction and allowing the circuit
to cool down. When the junction temperature (TJ) drops
below +145°C, normal operation resumes.
2: The standard output frequency is 30 kHz.
A 20 kHz output frequency option is
available upon request.
4.2
Motor Rotation Direction
The current-carrying order of the outputs depends on
the DIR pin state (“Rotation Direction”) and is illustrated
in Table 4-1. The DIR pin is not designed for dynamic
direction change during operation.
The thermal detection circuit has +25°C hysteresis.

4.10 Defining the Correct R
Value
PROG
The MTD6505 device has an overvoltage protection
function which detects when the VDD voltage exceeds
VOV = +7.2V. When this temperature is reached, the
circuit enters Thermal Shutdown mode and outputs
OUT1, OUT2 and OUT3 are disabled
This section explains how to define the correct KM
value for a specific fan. The KM is linked to the RPROG
(see Table 4-2). An incorrect KM selection can create
issues or reduce efficiency.

4.10.1
OPERATION
Follow the next steps to define the right RPROG value:
4.8
Internal Voltage Regulator
1. Apply a constant stream of air to a fan that is not
connected.
VBIAS voltage is generated internally and is used to
supply internal logical blocks. The VBIAS pin is used to
connect an external decoupling capacitor (1 µF or
higher). Notice that this pin is for IC internal use, and is
not designed to supply DC current to external blocks.
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):
4.9
Back Electromotive Force (BEMF)
Coefficient Setting
KM is the electro-mechanical coupling coefficient of the
motor (also referred to as “motor constant” or “BEMF
constant”). Depending on the conventions in use, the
exact definition of KM and its measurement criteria can
vary among motor manufacturers. To accommodate
various motor applications, the MTD6505 provides
options to facilitate diverse BEMF coefficients.
EQUATION 4-1:
KM COMPUTE
VP – P
K
= -------------
M
2f
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 nominal.
The MTD6505 defines BEMF coefficient (KM) as the
peak value of the phase-to-phase BEMF voltage,
normalized to the electrical speed of the motor. The
following table offers methods to set the KM value for
the MTD6505 device.
Note:
This is a theoretical procedure that does
not take care of the harmonics generated
by the BEMF. This information has to be
taken for indication only.

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.
Information contained in this publication regarding device
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.
