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
