* Small footprint 64 or 48 pin TQFP package Spindle driver is PWM during run and start Commutator is driven by a phase.
The actuator driver includes a saturation detector to monitor the loop compensation amplifier for saturation, an uncomm.
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 powe.
