LB1838M: Motor Driver, Low Saturation, Bidirectional, for Low Voltage Drive

The LB1838M is a low-saturation two-channel bidirectional motor driver IC for use in low-voltage applications. The LB1838M is a bipolar stepper-motor driver IC that is ideal for use in printers, cameras and other portable devices.

Features
  • Low voltage and wide operation (2.5V min)
  • Low saturation voltage (upper transistor + lower transistor residual voltage: 0.40V at 400mA)
  • Built-in through-current prevention circuit
  • Separate logic power supply and motor power supply
  • Built-in spark killer diodes
  • Built-in thermal shutdown circuit
