MTD6501C/D/G

3-Phase Brushless DC Sinusoidal Sensorless Fan Motor Driver

Features

Description

• Position Sensorless BLDC Drivers (No Hall

Sensor Required)

The MTD6501C/D/G devices are 3-phase, full-wave

drivers for brushless sensorless DC motors. They

feature 180° sinusoidal drive, high torque output, and

silent drive. Due to their adaptive features and wide

power-supply range capabilities (2V to 14V), they are

intended to cover a wide range of motor characteristics,

while requiring no external tuning from the user. Speed

control can be achieved through either power supply

modulation or pulse-width modulation (using the PWM

digital input pin).

• 180° Sinusoidal Drive, for High Efficiency and Low

Acoustic Noise

• Support 2V to 14V Power Supplies

• Speed Control Through PAM and/or PWM

• Built-in Frequency Generator (FG Output Signal)

• Built-in Lock-up Protection and Automatic

Recovery Circuit (External Capacitor not

Necessary)

Due to the compact packaging and minimum bill of

materials (power transistors incorporated, no Hall

sensor, no external tuning), they are best suited for low-

cost fan applications requiring high efficiency and low

acoustic noise, such as CPU cooling fans. Frequency

generator output enables precision speed control in

closed-loop applications. The MTD6501C/D/G drivers

include a Lock-up Protection mode, which turns off the

output current when the motor is under lock condition,

and an automatic recovery that enables the fan to run

when the lock condition is removed. Motor overcurrent

limitation, short-circuit protection and thermal-

shutdown protection are also included.

• Built-in Over Current Limitation and Short Circuit

Protection

• Built-in Thermal Shutdown Protection

• Thermally Enhanced SOP-8 Package for

MTD6501C and MTD6501G (Maximum Output

Current – 800 mA);

• MSOP-10L Package for MTD6501D (Maximum

Output Current – 500 mA)

• 20 kHz PWM Output Frequency for MTD6501C/D

and 23 kHz for MTD6501G

• Boost Mode (Optional Back Electromotive Force

(BEMF) Pre-amplification in MTD6501D)

The MTD6501C and the MTD6501G are available in a

compact thermally-enhanced SOP-8 package, while

the MTD6501D is available in the MSOP-10L package.

• No External Tuning Required

The MTD6501C/D/G devices are formerly products of

Advanced Silicon.
