System Motor Driver Series for CD・DVD・BD Players
3ch System Motor Driver
For Car Audio
BD8271EFV
General Description
BD8271EFV is 3ch power driver developed for driving
stepper motor and DC motor (or actuator coil). Blu-ray’s
motor & coil can be driven, when used along with 6ch
DVD power driver.
Features
■ Each driver of SLED (2ch) and Actuator (1ch) are
installed in a single-chip.
■ ON/OFF and the standby mode of 3ch can be
selected using two control terminals.
■ Built-in triangular wave generator circuit.
■ Adopts HTSSOP-B24 package that has high
power dissipation.
■ Built-in thermal shutdown function.
■ Highly effective SLED driver with PWM drive
system.
■ Built-in 2ch SLED driver that corresponds to the
stepper motor drive.
■ The actuator driver is linear BTL type.
