LB1843V_98 Datasheet, PDF (1/6 Pages) Sanyo Semicon Device – Low-saturation, current-controlled bidirectional motor driver

Ordering number: EN 4385B
Monolithic Digital IC
LB1843V
Low-saturation, current-controlled
bidirectional motor driver
Overview
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.

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}
needed and the IC is contained in a small SSOP-20 package
