BD7763EFV Datasheet (ROHM) - System Motor Driver

BD7763EFV, System Motor Driver

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 ne

BD7763EFV Features

* The hall sensor is not needed by 3-phase sensor less drive system.

* The spindle motor driver achieves stability high speed start by ROHM's own energizing method.

* Spindle, stepping and SA stepping achieve high efficiency drive by PWM control driver. The actua
