BD7763EFV driver equivalent, system motor driver.
* 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 metho.
* For Blu-ray drive
Features
* The hall sensor is not needed by 3-phase sensor less drive system.
* The spin.
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.
