半高无传感器系统电机驱动器IC

BD7763EFV是面向Blu-ray驱动器的主轴电机、执行器线圈、步进电机、球面像差调整用（SA）步进电机及负载电机驱动而开发的9ch系统电机驱动器IC。在主轴驱动器中采用无传感器驱动方式，无需用于电机位置检测的霍尔传感器（3个），因此适用于减少柔性电缆的接线及缩减外置零件。在执行器、负载驱动器、主轴、步进、SA输出段中使用功率MOSFET，可降低整机的功耗。 • The hall sensor is not needed by 3-phase sensor less drive system.\n• The spindle motor driver achieves stability high speed start by ROHM's own energizing method.\n• Spindle, stepping and SA stepping achieve high efficiency drive by PWM control driver. \nThe actuator is able to reduce power consu;
