Overview of A4975SLBTR-T

The A4975 is designed to drive one winding of a bipolar stepper motor in a microstepping mode. The outputs are rated for continuous output currents to ±1.5 A and operating voltages to 50 V. Internal pulse width modulated (PWM) current control combined with an internal three-bit nonlinear digital to-analog converter allows the motor current to be controlled in full-, half-, quarter-, or eighth-step (microstepping) modes. Nonlinear increments minimize the number of control lines necessary for microstepping. Microstepping provides increased step resolution, and reduces torque variations and resonance problems at low speed.Features and Benefits ▪ ±1.5 A continuous output current ▪ 50 V output voltage rating ▪ Internal PWM current control ▪ 3-bit nonlinear DAC ▪ Fast, mixed fast/slow, and slow current-decay modes ▪ Internal thermal shutdown circuitry ▪ Crossover-current and UVLO protection
