Overview

The LB1841V is a low-saturation current-controlled forward/reverse motor driver with provision for a constant voltage circuit using an external transistor and an output current limiter function. Its design is optimized for use in video camera loading motors.

Features

• Built-in output current limiter and detector circuit

• Built-in low-saturation voltage forward/reverse bridge circuit: V Osat = 0.40V typ. at 400 mA

• Little current drain in standby mode (up to 0.1 µA)

• Built-in low-saturation constant voltage circuit using an external pnp transistor

• Built-in reference voltage linked to input

• Built-in thermal shutdown circuit

• Low external parts count. Compact SSOP-20 package allows space saving design.
