LB1909MC: Stepping Motor Driver, Low Saturation Voltage, 12 V

The LB1909MC is a 2-channel low saturation voltage forward/reverse motor driver that can operate on a wide supply voltage range (2.5V to 16V). The IC is ideal for use in 2-phase excitation drive of general-purpose 2-phase bipolar stepper motors including dampers for refrigerators.

Features
  • Wide supply voltage range : 2.5V to 16V
  • Built-in shoot-through current protection circuit.
  • No standby current consumption (or zero).
  • Built-in thermal shutdown circuit.
  • Small package : SOIC10
  • Low saturation voltage : VO(sat) = 0.25V typ at IO = 200mA.
Benefits
  • Good safety margin for driving 12V motors
  • Rugged operation
  • Low Consumption, Saving energy
  • Thermal Protection
  • Industrial smallest package saves space on PCB.Flow mounting saves PCB cost.
