■ 제품사양

Motor
타입 = Stepper Motor Configuration = H Bridge Maximum Supply Voltage = 13.2 V
장착형태 = Surface Mount
패키지 = HTSSOP
핀수 = 54 Minimum Operating Supply Voltage = 10.8 V Product Width = 7.5mm BD7763EFV are 9ch system motor driver ICs, developed for the spindle motor, actuator coil, stepping motor, SA stepping motor and the loading motor drive of the Blu-ray drive. Since spindle driver adopts sensor less drive system and the hall sensor (3 pieces) of the motor position detection is not needed, it is suitable for making of flexible cable conserve wiring and the reductions of external parts. The actuator, loading driver, the spindle, stepping, and SA stepping use power MOSFET to reduce power consumption.The hall sensor is not needed by 3-phase sensor less drive system. The spindle motor driver achieves stability high speed start by ROHMs own energizing method. Spindle, stepping and SA stepping achieve high efficiency drive by PWM control driver. The actuator is able to reduce power consumption by using PWM drive system. The loading adopts forward/reverse-rotation drive system. ON/OFF of loading and other channels, brake mode of spindle driver, and stand-by mode are selectable by the two control terminals. Built-in thermal-shut down circuit. Improved heat radiation efficiency utilizing lm-type HTSSOP package with good thermal conductivity.
