LB1840M
Low-voltage/Low-saturation Bidirectional
Variable Constant-voltage Motor Driver
Overview
The LB1840M is a low-voltage, low-saturation, three-input
type two-channel bidirectional motor driver that permits
switching between constant-voltage regulated output and
saturated output. The design is ideal for a two-phase bipolar
driver for stepping motors.
