BD8256EFV-M - 9ch System Motor Driver

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.

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.
