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.

(Note 1) This is applicable to pins MUTE1245 and MUTE3.
(Note 2) This is applicable to pins IN1, IN2, IN3, IN4, IN5, and BIAS.
(Note 3) Glass epoxy substrate dimensions are 70mm×70mm×1.6mm, 1 layer substrate, (Copper foil 0mm×0mm)
Reduce power dissipation capability by 8.8mW for each degree above 25°C.
(Note 4) Glass epoxy substrate dimensions are 70mm×70mm×1.6mm, 4 layer substrate, (Copper foil 70mm×70mm)
Reduce power dissipation capability by 32.0mW for each degree above 25°C.
Caution:
Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is
operated over the absolute maximum ratings.
