PRELIMINARY HDD PRODUCTS KA3120 SPINDLE & VOICE COIL MOTOR ONE CHIP DRIVER The KA3120 is an ASIC combination chip, which was designed for the HDD, includes the following functions: spindle motor drive, voice coil motor drive, retract and power management.
To drive and control the spindle, the digital ASIC provides the appropriate control signals (Start up, commutation, speed control) to the KA3120.
The spindle motor condition is monitored by the FG output and the motor speed control is accomplished via the PWMSP input.
