Driver
Overview
The LB11948T is a low saturation voltage output PWM current control bipolar drive stepping motor driver. It is optimal
for use as the driver for the miniature low-voltage stepping 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
