Monolithic Digital IC

LB1843V

Low-saturation, current-controlled

bidirectional motor driver

Overview

Package Dimensions

unit : mm

The LB1843V is a low-saturation bidirectional motor driver

with output current limitation and detection functions. This

design is ideal for controlling the loading motor in a video

camera.

3179A-SSOP20

[LB1843V]

Features

Output current limiter and detector built in

Low-saturation voltage bidirectional bridge circuit built in:

V_Osat = 0.40 V typ. at 400 mA

Practically no current drain (0.1 µA or less) in standby mode

Input-linked reference voltage built in

Thermal shutdown circuit built in

Requires little space, since few external components are
