LB1649

Dual Bidirectional Motor Driver

Overview

The LB1649 is a dual bidirectional motor driver. Since
each channel has a 2-input logic circuit and performs
bidirectional driving and braking functions, it is capable
of direct driving 2pcs. of motor of various types rated at
6 to 24V.
The output voltage can be varied by using external zener
diodes.
It is especially suited for dual motor drive (reel motor,
loading motor, cassette motor in VCR) and for stepping

motor drive.

Features

• With power transistor for motor drive contained,
capable of withstanding dash current of 1A max.

• Performs braking function at the motor stop mode.

• Contains elements to absorb motor dash current.

• Input connectable dirct to MOS LSI.

• Minimun number of external parts required.

• Wide operating voltage range.
