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 (R_PROG) Setting

to fit Motor Constant (K_M) 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
