Description:

Spindle/VCM Controller and Pre-driver

Features

* Small footprint 64 or 48 pin TQFP package Spindle driver is PWM during run and start Commutator is driven by a phase lock loop for high jitter immunity Adjustable slew rate to minimize stress in the power MOSFE

Applications

* The actuator driver includes a saturation detector to monitor the loop compensation amplifier for saturation, an uncommitted opamp for input signal conditioning, a voltage reference to provide a precise voltage level for internal PWM buffers, and reduced power dissipation. The spindle driver includ
