9ch System Motor Driver

For Car AV

BD8256EFV-M

General Description

Key Specifications

 Ron(Spindle):

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.

1.0Ω(Typ)

1.5Ω(Typ)

4.5V to 10.5V

 Ron(Loading):

 Power Supply Voltage Range:

It has a built-in Serial Peripheral Interface (SPI) with a

max clock frequency of 35MHz, for interfacing with the

Micro-controller.
