Monolithic Digital IC

Low-Saturation Bidirectional Motor Driver

for Low-Voltage Drive

LB1838JM

Overview

The LB1838JM is a low-saturation two-channel bidirectional motor driver IC for use in low-voltage applications.

It has a wide operating temperature range of -40 to 80

°C and is ideal for 2-phase excitation bipolar stepping motor driver

IC used in automotive components (other than critical safety parts), consumer and industrial products, and many other

applications.

Features

• Low voltage operation (2.5V min)

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

• 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)
