1 / 5 page 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. Features . Wide operating voltage range (3.0 to 9.0 V). . Low saturation voltage VO (sat) = 0.40 V at IO = 200 mA. . Consumes almost no current in standby mode (0.1 µA or less). . Permits setting of bidirectional constant-voltage regulated value. . Built-in reference voltage coupled to input. . Brake function built in. . Compact MFP14S package.
