Features
鈥?120擄 voltage linear system
鈥?Appropriate for portable applications, since the
LB1881M reduces system power requirements by using
motor voltage control for speed control.
鈥?Built-in torque ripple compensation circuit
鈥?Small external capacitances due to the adoption of a soft
switching technique (chip capacitor).
鈥?Built-in thermal shutdown circuit
鈥?Built-in FG amplifier
