LB1839M Low-
voltage/Low-saturation Bidirectional Constant-
Voltage Regulated Motor Driver
Overview
The LB1839M 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 of the LB1839M is ideal for a two-phase bipolar driver for stepping motors.
