Overview
The LB1881M 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 LB1881M 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
