Monolithic Digital IC
LB1645N
Bidirectional Motor Driver
Overview
The LB1645N is a bidirectional motor driver IC. Since it
has a 2-input logic circuit and performs the function of
bidirectional driving and braking, it is capable of direct
driving 6V, 9V, 12V motors. The output voltage can be
varied by using an external Zener diode.
