MTD6505

Sinusoidal Sensorless 3-Phase Brushless DC Fan Motor Driver

Features

Description

• 180° Sinusoidal Drive, for high efficiency and low

acoustic noise

The MTD6505 device is

3-phase full-wave

sensorless driver for brushless DC (BLDC) motors. It

features 180° sinusoidal drive, high torque output and

silent drive. With the adaptive features, parameters and

wide range of power supplies (2V to 5.5V), the

MTD6505 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

• Programming Resistor (R_PROG) setting to fit motor

constant (Km) range from 3.25 mV/Hz to

52 mV/Hz

The compact packaging and the minimal bill-of-

material make the MTD6505 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.

• Direction Control:

- Forward direction: connect DIR pin to GND or

leave floating

- Reverse direction: connect DIR pin to V_BIAS

or 3V

• Speed Control through Power Supply Modulation

(PSM) and/or Pulse-Width Modulation (PWM)

The MTD6505 device includes Lockup 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.

• Built-in Frequency Generator (FG Output Signal)

• Built-in Lockup Protection and Automatic

Recovery Circuit

• Built-in Overcurrent Limitation

• Built-in Thermal Shutdown Protection

• Built-in Over Voltage Protection

• No External Tuning Required

The MTD6505 is available in a compact, thermally

enhanced, 3mm x 3mm 10-lead UDFN package.
