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.
