MTD6502B

MTD6502B 5V 3-Phase BLDC Sinusoidal Sensorless Fan Motor Driver Features: Position Sensorless BLDC Drivers (No Hall Sensor Required) 180° Sinusoidal Drive, for High Efficiency and Low Acoustic Noise Support 2V to 5.5V Power Supplies Direction Control: - Forward direction: connect DIR pin to GND or leave floating - Reverse direction: connect DIR pin to VDD Speed Control through Power Supply Modulation (PSM) and/or Pulse-Width Modulation (PWM) 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 Description: 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 is intended to cover a wide range of motor characteristics, while requiring minimum external components. Speed control can be achieved through either power supply modulation or pulse-width modulation (using the PWM digital input pin). With the compact packaging and minimum bill-ofmaterial (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 ...
