Introduction

The LB1838M is a low-saturation two-channel bidirectional motor driver IC for use in low-voltage applications. The LB1838M is a bipolar stepper-motor driver IC that is ideal for use in printers, FDDs, cameras and other portable devices.

Features

• Low voltage operation (2.5 V min)
• Low saturation voltage (upper transistor + lower transistor residual voltage; 0.40 V at 400 mA)
• Through-current prevention circuit built in
• Separate logic power supply and motor power supply
• Spark killer diodes built in
• Thermal shutdown circuit built in
• Compact package (14-pin MFP)

Applications

• printers
• FDDs
• cameras
• other portable devices
