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)
