Description
The KA3012D is a monolithic IC, and suitable for 4-CH motor driver which drives sled motor, loading motor, focus & tracking actuator of CD-media system and built in OP-amp which can receive digital signal from servo of CD-media system.

Features
• BTL (H-Bridge type linear) 4channel motor driver
• Wide dynamic range:
    - SVCC=12V, PVCC1=5V, RL=8Ω → VOM=4.2V
    - SVCC=12V, PVCC2=12V, RL=24Ω → VOM=10.4V
• Built in level-shift circuit
• Built in OP-amp for digital input
• Built in thermal shutdown (TSD) circuit
• Three independent sources
• Low crossover distortion
• Built-in reverse rotation prevented
• Built-in short breaker

Typical Applications
• Compact disk ROM (CD-ROM)
• Compact disk RW (CD-RW)
• Digital video disk ROM (DVD-ROM)
• Digital video disk RAM (DVD-RAM)
• Digital video disk player (DVDP)
• Other compact disk media
