Sanyo LB1851M Specifications
Ordering number:EN3659
Monolithic Digital IC
LB1851M
3-Phase Brushless Motor Driver
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.
