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
• 120˚C 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.
