MTD6502B-L Datasheet PDF - Microchip Technology

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).

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

APPLICATIONs:
• Notebook CPU Cooling Fans
• 5V 3-Phase Brushless DC Motors
