Overview

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.

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