Sanyo LB1833M Specifications

Ordering number:EN3297

Monolithic Digital IC

LB1833M

Low-Saturation Bidirectional Motor Driver

for Low-Voltage Applications

Overview

The LB1833M is a low-saturation stepping motor driver
IC for use in low-voltage applications. It is especially
suited for use in portable equipment such as printer,

FDD, camera.

Features

• Capable of being operated from a low voltage (2.5V
min).

• Low saturation voltage.

(Upper transistor+low transistor residual voltage 1.0V
max at 400mA).

• Through current preventer on-chip.

• Logic power supply and motor power supply are
sepatate.

• 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.
