MTD6508  
3-Phase Sinusoidal Sensorless Brushless DC Fan Motor Driver  
Features  
Description  
• 180° Sinusoidal Drive for High Efficiency and Low  
Acoustic Noise  
The MTD6508 device is a 3-phase, full-wave  
sensorless driver for brushless DC (BLDC) motors. It  
features a 180° sinusoidal drive, high torque output and  
silent drive. With adaptive features, parameters and a  
wide range of power supplies (2V to 5.5V), the  
MTD6508 is intended to cover a broad range of motor  
characteristics while requiring minimum external  
components. Speed control can be achieved through  
either power supply modulation (PSM) or pulse-width  
modulation (PWM).  
• Position Sensorless BLDC Drivers  
(no Hall Effect Sensor required)  
• Integrated Power Transistors  
• Supports 2V to 5.5V Power Supplies  
• Variable Programming Resistor (RPROG) Setting  
to fit Motor Constant (KM) Range from 3.25 mV/  
Hz to 52 mV/Hz  
• Speed Control through Power Supply Modulation  
(PSM) and/or Pulse-Width Modulation (PWM)  
Compact packaging and a minimal bill of materials  
make the MTD6508 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.  
• Built-in Frequency Generator: FG, FG/3 Output  
Signal (FG/2 and FG/6 Option are available upon  
request)  
• Output PWM Slew Rate Control Programmable  
with an External Resistor for Start-up  
(Adjustable version)  
The MTD6508 device includes Lock-up 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.  
• Phase Target Selection for Regulation  
(Adjustable Version)  
• Start-up Strength Selection (Adjustable Version)  
• Start-up Output Current Controlled by PWM  
• Output Current Soft Start  
The MTD6508 is available in compact, thermally-  
enhanced, 10-Lead 3 mm x 3 mm x 0.5 mm UDFN  
packages and 16-Lead 4 mm x 4 mm x 0.5 mm  
UQFN packages.  
• Built-in Lock-up Protection and Automatic  
Recovery Circuit  
• Built-in Overcurrent Limitation  
• Built-in Thermal Shutdown Protection  
• Built-in Overvoltage Protection  
• Low Minimal Start-up Speed for Low-Speed  
Operation  
• Packages:  
- 10-Lead 3 mm x 3 mm x 0.5 mm UDFN  
- 16-Lead 4 mm x 4 mm x 0.5 mm UQFN  
(Adjustable version)  
Applications  
• Notebook CPU Cooling Fans  
• 5V 3-Phase BLDC Motors
