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.
