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
