EVLPOWERSTEP01

EVLPOWERSTEP01 System-in-package integrating microstepping controller and 10 A power MOSFETs demonstration board Data brief Description The EVLPOWERSTEP01 demonstration board is a microstepping motor driver delivering up to 10 Ar.m.s.. In combination with the STEVALPCC009V2 communication board and the evaluation software, the board allows the user to investigate all the features of the powerSTEP01. In particular, the board can be used to check the performance and to regulate the parameters in order to fit the application requirements. The EVLPOWERSTEP01 supports the daisy chain configuration making it suitable for the evaluation of the powerSTEP01 in multi motor applications. Features  Voltage range from 10.5 V to 85 V  10 Ar.m.s. maximum output current  Up to 1/128 microstep  Programmable speed profile and advanced commands  Adjustable output slew rate  SPI with daisy chain feature  FLAG and BUSY LED indicators  Flexible supply voltage management  Suitable to be used in combination with STEVAL-PCC009V2 Applications  High power bipolar stepper motors: – Stage lighting – Surveillance systems – Textile and sewing machines – Pick and place machines October 2014 DocID027006 Rev 1 For further information contact your local STMicroelectronics sales office. 1/8 www.st.com Board description EVLPOWERSTEP01 Board description Table 1.
