Overview
The LB1841V is a low-saturation current-controlled
forward/reverse motor driver with provision for a constant
voltage circuit using an external transistor and an output
current limiter function. Its design is optimized for use in
video camera loading motors.
Features
Built-in output current limiter and detector circuit
Built-in low-saturation voltage forward/reverse bridge
circuit: VOsat = 0.40V typ. at 400 mA
Little current drain in standby mode
(up to 0.1
μA)
Built-in low-saturation constant voltage circuit using an
external pnp transistor
Built-in reference voltage linked to input
Built-in thermal shutdown circuit
Low external parts count. Compact SSOP-20 package
allows space saving design.
