  • Product introduction

A4941 三相电动机drive整合了 BEMF 感应，在风扇应用中无需Hall sensor。

提供脉冲调制 (PWM) 输入控制电动机速度，无需外部可变电源，从而节省系统成本。PWM 输入也可作为开关使用，以终止电动机工作，使 IC 进入功耗较低的待机模式。

A4941 采用 16 引脚 TSSOP 封装（后缀 LP），并安装有外露散热板。其封装为无铅产品，且采用 100% 雾锡电镀。

  • 无传感器（无需霍尔传感器）
  • 软开关，减少可闻噪音
  • Minimal external components
  • PWM 速度输入
  • FG 速度输出
  • 低功耗待机模式
  • 锁检测
  • 可选过流保护
