LB11948T: PWM Current Control Stepping Motor Driver

The LB11948T is a low saturation voltage output PWM current control bipolar drive stepper motor driver. It is optimal for use as the driver for the miniature low-voltage stepper motors used in portable electronic equipment such as portable thermal printers.

Features
  • PWM current control (external excitation)
  • Simultaneous on state prevention function (through current prevention)
  • Thermal shutdown circuit
  • Noise canceller function
  • Low-power mode control pin
