Descriptions:

The LB1663 is a unipolar stepper motor driver IC designed by SANYO for controlling 4-phase stepper motors. It integrates logic control and power output stages, simplifying motor drive circuit design. The IC supports full-step and half-step driving modes and is suitable for low-power stepper motor applications.

Features:

• 4-Phase Unipolar Drive: Compatible with standard unipolar stepper motors.
• TTL-Compatible Inputs: Easy interfacing with microcontrollers or logic circuits.
• Built-in Clamp Diodes: Protects against back EMF from motor coils.
• Thermal Shutdown: Prevents damage from overheating.
• Low Saturation Voltage: Improves efficiency and reduces power dissipation.
• Wide Operating Voltage Range: Supports 4.5V to 15V power supply.

This IC is commonly used in printers, office automation equipment, and small robotics applications.
