MTD6502B集成电路（IC）的电机驱动器控制器规格书PDF中文资料

MTD6502B属于集成电路（IC）的电机驱动器控制器。由微芯科技股份有限公司制造生产的MTD6502B电机驱动器，控制器产品属于电机驱动器和控制器电源管理集成电路 (PMIC) 系列，可用于控制或操作从某电源施加到电机或相关机电执行器的电源。所实现的具体功能和特性集根据预期负载和预期应用的特性有很大差异，范围从用于有刷电机的简单开环速度控制到基于步进电机的高级闭环运动控制。

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
