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
