**TECHNICAL DATASHEET   Astrosyn** 

## **HIGH PERFORMANCE MICROSTEPPING DRIVER MODEL P542A** 

Model P542A is a full digital high performance DSP driver suitable for 2-phase and 4-phase hybrid steppers requiring a drive current of up to 5.6A/phase.  The design features an advanced bipolar constant-current chopper circuit with current control technology.  This driver is suited to stepper motor control applications requiring low noise, low vibration, high speed and high precision. 

- ➢ Supply voltage 20V to 50Vdc 

- ➢ Inaudible chopping frequency 

- ➢ Drive current from 1.7A to 5.6A 

- ➢ Automatic idle current reduction 

- ➢ Mixed-decay current control for reduced motor heating 

- ➢ 16 selectable step resolutions in decimal and binary 

- ➢ Microstepping to 40,000 steps/revolution 

- ➢ Suitable for 4, 6 or 8 lead wire motors 

- ➢ Over temperature and over voltage protected 

- ➢ Short circuit protected 

- ➢ Compact size
