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:
VOsat = 0.40 V typ. at 400 mA
.
Practically no current drain (0.1 A 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
