MTD6505集成电路（IC）的电机驱动器控制器规格书PDF中文资料

MTD6505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MTD6505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。

描述 Description

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.
