Dual Bidirectional Motor Driver
Overview
The LB1651 is a dual bidirectional motor driver that is
designed to drive motors directly by TTL outputs. It provides
the functions of bidirectional motor drive, brake that are
determined by two inputs and the inhibit function that brings
the output to a high impedance state.
Applications
.
Multi DC motor driver
.
