Overview
8980 SUPERSERVO™ SPINDLE & VOICE-COIL ACTUATION MANAGER/DRIVER
8980
TM
The A8980CJT provides complete drive, management, and control of the voice-coil and spindle motor power actuation subsystems used in hard disk drives.
Extensive programmable control features and system diagnostics are provided via a serial interface under the direction of an external microcontroller.
The large-scale integration and use of advanced DABiC™ (digital/analog-BiCMOS) merged technologies results in minimum power dissipation, minimum operating voltage requirements, and minimum external components.
The spindle drive function incorporates a three-phase MOS power driver and a back-EMF sensing motor commutation sche...
