Structure
:
Product Name :
Silicon Monolithic Integrated Circuit
Power Driver For DVD Players
Device Name : BA5956FM
Features
: • 2CHs for current driving-type BTL drivers to drive two-axis actuators
1CH for a voltage driving-type BTL driver for a feed motor
1CH for a voltage driving-type BTL driver for a loading motor
1CH for a voltage driving-type BTL driver for a spindle motor
• Use of the HSOP-M36 power package achieves downsizing of the set.
• A wide dynamic range
• A built-in thermal shutdown circuit installed.
• A built-in mute circuit installed. (This circuit can mute the outputs of the drivers
except for those for loading motors.)
• The power supplies for PreVcc, the actuator part, the loading part, and PowVcc
of the feed motor part/spindle motor part are provided independently to achieve
an efficient drive.
