System Motor Driver Series for CD・DVD・BD Player
6ch System Motor Driver
For Car AV
BD8255MUV-M
General Description
BD8255MUV-M is a 6ch motor driver developed for
driving coil actuator (2ch), sled motor (2ch), a loading
motor, and a three-phase motor for spindle. This can
drive the motor and coil of CD/DVD 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 loading driver short-circuit protection
