Low-voltage/Low-saturation Bidirectional

Constant-Voltage Regulated Motor Driver

Overview

The LB1837M is a low-voltage, low-saturation, two-channel

motor driver with a bidirectional braking function that provides

constant-voltage regulated output for bidirectional operation.

The design of the LB1837M is ideal for video equipment,

cameras, and other portable equipment.
