LB1831M
Low-Saturation Bidirectional Motor Driver
for Low-Voltage Applications
Overview
Package Dimensions
The LB1831M is a dual low-saturation bidirectional
motor driver IC for use in low-voltage applications. It is
especially suited for use in compact low-voltage motors
in portable equipment such as printer, FDD, camera.

[LB1831M]
Features
• Capable of being operated from a low voltage (2.5V
min).
• Low saturation voltage.
(Upper transistor+lower transistor residual voltage
1.0V max at 400mA).
• Parallel connection avaiable.
(Upper transistor+lower transistor residual voltage
0.5V max at 400mA).
(Upper transistor+lower transistor residual voltage
1.0V max at 800mA).
• Logic power supply and motor power supply are
separate.
• On-chip braking function.
• On-chip spark killer diodes.
• Possible to increase the internal allowable power
dissipation because the package is compact (MFP16FS) and heat can be radiated easily to the outside.
