Overview
The LB1945D is a PWM current control stepping motor driver that uses a bipolar drive technique. It is optimal for use with the carriage and paper feed stepping motors used in printers.
Functions and Features
⢠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
