Overview
Ordering number: EN3950C Monolithic Digital IC 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.
