MTD6502B  
5V 3-Phase BLDC Sinusoidal Sensorless Fan Motor Driver  
Features:  
Description:  
• Position Sensorless BLDC Drivers  
(No Hall Sensor Required)  
The MTD6502B device is a 3-phase full-wave driver for  
brushless sensorless DC motors. It features 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 MTD6502B device  
• 180° Sinusoidal Drive, for High Efficiency and Low  
Acoustic Noise  
• Support 2V to 5.5V Power Supplies  
• Direction Control:  
is intended to cover  
a wide range of motor  
characteristics, while requiring minimum external com-  
ponents. Speed control can be achieved through either  
power supply modulation or pulse-width modulation  
(using the PWM digital input pin).  
- Forward direction: connect DIR pin to GND or  
leave floating  
- Reverse direction: connect DIR pin to VDD  
• Speed Control through Power Supply Modulation  
(PSM) and/or Pulse-Width Modulation (PWM)  
With the compact packaging and minimum bill-of-  
material (integrated power transistors, no Hall sensor,  
no external tuning), the MTD6502B is best suited for  
low-cost fan applications requiring high efficiency and  
low acoustic noise, such as notebook CPU cooling  
fans. Frequency generator (FG) output enables the  
precision speed control in closed-loop applications.  
The MTD6502B driver includes a lock-up protection  
mode, which turns off the output current when the  
motor is under lock condition, and an automatic recov-  
ery that enables the fan to run when the lock condition  
is removed. The motor overcurrent limitation and ther-  
mal-shutdown protection are included for safety-  
enhanced operations.  
• Built-in Frequency Generator (FG Output Signal)  
• Built-in Lock-up Protection and Automatic  
Recovery Circuit (External Capacitor not  
Necessary)  
• Built-in Over Current Limitation  
• Built-in Thermal Shutdown Protection  
• No External Tuning Required  
• Available Packages:  
- 3 mm x 3 mm TDFN-10  
Applications:  
The MTD6502B is available in a compact thermally-  
enhanced 3 mm x 3 mm TDFN package.  
• Notebook CPU Cooling Fans  
• 5V 3-Phase Brushless DC Motors
