A89301 是一款三相无传感器无刷直流（BLDC）电机驱动器（栅极驱动器），工作电压范围 5.5 - 50V，是Allegro 首批 QuietMotion 解决方案之一。A89301 是吊扇、底座风扇、浴室排气扇和高级家用电器风扇和泵的理想选择。
完全集成定向磁场控制 (FOC) 的算法可以实现最佳效率和噪声性能。该器件可在静止状态、风车状况甚至反向风车状态下优化电机启动性能。
电机速度通过模拟、PWM 或 CLOCK 输入控制。可选闭环速度控制，可对 RPM 到时钟频率比进行编程设置。
提供简单的 I2C 接口，用于设置电机额定电压、额定电流、额定速度、电阻和启动曲线。I2C 接口还用于开/关控制、速度控制和速度回读。
A89301 采用 24 触点 4 mm×4 mm QFN 封装，带外露散热焊盘（后缀 ES）。该封装为无铅封装，采用 100% 雾锡电镀引脚框。
