Description
Ordering number : EN4385D
LB1843V
Monolithic Linear IC
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.

Function
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 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
SSOP20 (225mil)
