Stepper Motor Control
Stepper motors have become the motor of choice in a
variety of open loop applications where accuracy, repeatability and
maintenance-free operation rather than high speed and acceleration
are key.
Toshiba's stepper
motor ICs combine drive capability with functions that allow control
overhead to be offloaded from the host microcontroller. The devices
feature internal PWM current control and offer drive modes for 1/2, 1/8
and 1/16 step operation. Parts with selectable mixed decay modes allow
designers to minimise both audible noise and vibration by minimising PWM
ripple on the microstepping output.
