LB1838M
Monolithic Digital IC
Low-Voltage, Low-Saturation
Bidirectional Motor Driver
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, cameras and other portable devices.
Functions
