MTD6505

3-Phase Sinusoidal Sensorless Brushless Motor Driver

Features

Description

• 180° Sinusoidal Drive for High Efficiency and Low

Acoustic Noise

The MTD6505 device is a 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 PSM or PWM.

• Position Sensorless BLDC Drivers

(no Hall Effect Sensor required)

• Integrated Power Transistors

• Supports 2V to 5.5V Power Supplies

• Programming Resistor (R_PROG) Settings to Fit

Motor Constant (K_M) Range from 3.25 mV/Hz to

52 mV/Hz

The compact packaging and the minimal bill of

materials 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)

• Built-in Frequency Generator (FG Output Signal)

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 Lockup Protection and Automatic

Recovery Circuit

• Built-in Overcurrent Limitation

• Built-in Thermal Shutdown Protection

• Built-in Overvoltage Protection

• No External Tuning Required

• Available Package:

The MTD6505 is available in a compact, thermally-

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