Three-Phase Brushless Motor Driver IC
LB1881V
Overview
The LB1881V is a three-phase brushless motor driver IC
designed for use as a camcorder capstan or drum motor
driver, or as a digital audio tape player/recorder motor
driver.
Features
120° voltage linear system
Appropriate for portable applications, since the
LB1881V reduces system power requirements by using
motor voltage control for speed control.
Built-in torque ripple compensation circuit
Small external capacitances due to the adoption of a soft
switching technique (chip capacitor).
Built-in thermal shutdown circuit
Built-in FG amplifier
