Product Description
- Description
- The A3955 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 transient-suppression diodes
- ▪ Internal thermal shutdown circuitry
- ▪ Crossover-current and UVLO protection
