LB1651

Ordering number: EN2637C Monolithic Digital IC LB1651 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. Package Dimensions unit : mm 3037A-DIP20H [LB1651] Applications . Multi DC motor driver . Bidirectional motor driver . Bipolar stepping motor driver Features . High output current (1 A/ch) . Wide operating voltage range (4.5 to 36 V) . Inhibit function . Direct drive made possible by TTL, CMOS IC .
