Monolithic Digital IC
Low-Saturation Bidirectional Motor
Driver for Low-Voltage Drive
LB1836M
Overview
The LB1836M is a low-saturation two-channel bidirectional motor driver IC for use in low-voltage applications.
The LB1836M is a bipolar stepper-motor driver IC that is ideal for use in printers, FDDs, cameras and other portable
devices.
Features
• Low voltage operation (2.5V min)

• Parallel connection (Upper transistor + lower transistor residual voltage ; 0.5V typ at 800mA).
• Separate logic power supply and motor power supply
• Brake function
• Spark killer diodes built in
• Thermal shutdown circuit built in
• Compact package (14-pin MFP)
