LB1838JM
Monolithic Digital IC
Low-Saturation Bidirectional Motor Driver
for Low-Voltage Drive
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)
