System motor driver for CD/DVD Player
5ch System Motor Driver
for Car AV
BD8205EFV-M
General Description
BD8205EFV-M is a 5-Channel system motor driver
developed for DC motors (Spindle motor, Sled motor,
Loading motor) and coils (Tracking, Focus) drive for
actuator. This IC can drive the motor and the coil of a
CD/DVD drive.
Features
■ 5CH BTL Driver
■ POWVCC1 for CHs 1, 2, and 3 (DC motors) and
POWVCC2 for CHs 4 and 5 (actuator) are
independent for efficient drive configuration.
■ Built-in protection functions (TSD, UVLO, BIAS
Drop Mute)
■ AEC-Q100 Qualified

3. Shut-down Sequence
(1) Turn off the driver input and the mute control input.
(2) Turn off the reference voltage input (BIAS). Because BIAS is sequence-free, turn off after the power supply turn off is
possible.
(3) The slew rate recommends more than -0.045V/μs in the shut-down after the power supply voltage lower than 5V.
When the power supply voltage quickly shut-down, the discharge current from CVREG becomes the overcurrent and
may lead to internal element destruction. Keep relations of POWVCC1 >= POWVCC2 at the shut-down also.
