BD7763EFV Description

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,...
