LB1837M: Low-Voltage/Low-Saturation Bidirectional Constant-Voltage Regulated Motor Driver

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/still cameras and other portable equipment.

Features
  • Wide operating voltage range (3.0 to 9.0V)
  • Low saturation voltage VO (sat) = 0.40V at IO = 200mA
  • Consumes almost no current in standby mode (0.1µA or less)
  • Permits setting of bidirectional constant-voltage regulated value
  • Built-in reference voltage coupled to input
  • Brake function built in
  • Compact MFP14S package
Applications
  • Video cameras
  • Still cameras
  • Other portable equipment
