LB1946: PWM Current Control Stepping Motor Driver

A stepping motor driver IC that implements PWM current control bipolar drive with a fixed off time. This IC features 15-current setting levels using a fixed VREF voltage and supports for micro-stepping drive from 1-2 phase excitation to 4W1-2 phase excitation drive. This device is optimal for driving stepping motors such as those used for carriage drive and paper feed 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
