LB1843V Datasheet, PDF (1/10 Pages) Sanyo Semicon Device – Low-saturation, current-controlled bidirectional motor driver

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

Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time.
Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current,
high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details.
Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed,
damage may occur and reliability may be affected.
