LD7000

Spindle/VCM Controller and Pre-driver

LD7000 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

LD7000 General Description

The LD7000 Servo and Spindle Predriver, a CMOS monolithic integrated circuit housed in a 64-lead TQFP package operates from +5 V and +12 V supplies. It is designed to drive a voice coil actuator and a 3-phase, Hall-sensorless motor with external power MOSFETs. The device is intended for use in 12 V .
