[LB1851M]
Overview
The LB1851M is a 3-phase brushless motor drive IC
ideally suited for use in VCR capstan motor driver, drum
motor driver, and DAT motor driver applications.
Features
120C voltage linear type.
Less power dissipation because of speed control based
on motor voltage control (suitable for use in portable
sets).
Torque ripple compensation circuit on chip.
Small capacitance of external capacitor because of soft
switching method (clip capacitor).
Thermal shutdown circuit on chip.
FG amplifier on chip.
