LB1838M
Low-saturation, Bidirectional Motor Driver
for Low-voltage Applications
Overview
The LB1838M is a low-saturation two-channel bidirectional
motor driver IC for use in low-voltage applications.
The LB1838M is a bipolar stepper-motor driver IC that is ideal
for use in printers, FDDs, cameras and other portable devices.
