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)

• Low saturation voltage (upper transistor + lower transistor residual voltage ; 0.40V typ at 400mA).

• 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)
