Monolithic Linear IC
Low-voltage/Low-saturation Bidirectional Constant-Voltage Regulated Motor Driver
http://onsemi.com
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.
Function
• 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.
