Monolithic Digital IC
LB1641
Bidirectional Motor Driver
Overview
The LB1641 is a bidirectional motor driver IC. Since it has a 2-input logic circuit and performs the functions 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.
Features
• 2-input logic can be used to exercise control of bidirectional driving and braking.
• On-chip elements to absorb dash current of motor.
• Input interfaceable to MOS LSI.
• Output voltage variable by use of external zener diode.
