KA3012D - 4-Channel Motor Driver

General 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 OPamp which can receive digital signal from servo of CDmedia system.

Key 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.
