MONOLITHIC CD-ROM/DVD-ROM 3-PHASE SPINDLE MOTOR DRIVER

DESCRIPTION The µPD16882 is a CD-ROM/DVD-ROM 3-phase spindle motor driver consisting of a CMOS controller and MOS bridge outputs. By employing 3-phase full-wave PWM as the drive method and MOSFETs at the output stage, it has been possible to reduce the power consumption of the µPD16882 ever furt

MOS INTEGRATED CIRCUIT

FEATURES • Supply voltage for controller block: 5 V, supply voltage for output block: 12 V • Low on-state resistance (total on-state resistance of upper and lower transistors) output RON = 1.1 Ω (TYP.) • Low power consumption due to 3-phase full-wave PWM drive method • On-chip hole bias switch
