For Car AV
BD8256EFV-M
General Description
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.
Features
Built-in Serial Peripheral Interface(SPI)
High efficiency at 180° PWM for spindle driver
Built-in 2-channel stepping motor driver for sled
Built-in actuator over current protection circuit
Built-in loading driver short-circuit protection
AEC-Q100 Qualified
