LD7000 Overview
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 disk drive applications.
