Overview

Ordering number : ENN4384A LB1841V Monolithic Digital IC LB1841V Low-Saturation Current-Controlled Forward/Reverse Motor Driver 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.
Package Dimensions unit: mm 3179A-SSOP20 [LB1841V] 20 11 4.
4 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.
