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 V_DD

• 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
