LB1946: PWM Current Control Stepping Motor Driver
A stepping motor driver IC that implements PWM current control bipolar drive with a fixed off time. This IC features 15-current setting levels using a fixed VREF voltage and supports for micro-stepping drive from 1-2 phase excitation to 4W1-2 phase excitation drive. This device is optimal for driving stepping motors such as those used for carriage drive and paper feed in printers.
特性
- 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
