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

• 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.
