LB1945D: PWM Current Control Type Stepping Motor Driver

The LB1945D is a PWM current control stepping motor driver that uses a bipolar drive technique. It is optimal for use with the carriage and paper feed stepping motors used in printers.

特性
  • PWM current control (external clock)
  • Digital load current selection function (supports 1-2, W1-2, and 2-phase excitation)
  • Built-in high and low side diodes
  • Simultaneous on state prevention function (through-current prevention)
  • Built-in thermal shutdown circuit
  • Noise canceling function
