9ch System Motor Driver For Car AV - BD8256EFV-M
BD8256EFV-M is a 9ch motor driver developed for driving coil actuator (3ch), sled motor (2ch), a loading motor, and a three-phase motor for spindle. This chip has a built-in 2ch LVDS (Low Voltage Differential Signaling) output for spherical aberration. This can drive the motor and coil of blu-ray drive.
It has a built-in Serial Peripheral Interface (SPI) with a max clock frequency of 35MHz, for interfacing with the Micro-controller.
