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 (MFP-16FS) and heat can be radiated easily to the outside.
