Monolithic Digital IC
LB1650
Dual Bidirectional Motor Driver
Overview
The LB1650 is a dual bidirectional motor driver that is
designed to accept standard TTL input logic levels and
drive motors. 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.
• Bidirectional motor driver.
• Bipolar stepping motor driver.
Features
• High output current (1A/ch).
• Wide operating voltage range (4.5 to 36V).
• Inhibit facility.
• Input connectable to TTL, CMOS IC.
• High noise margin.
