PowerSTEP01 system-in-package integrating microstepping controller and 10 A
power MOSFETs evaluation board
Introduction
The
EVLPOWERSTEP01
evaluation board is based on the powerSTEP01 system-in-package implementing a complete stepper
motor driver for high power applications. It is designed to operate with a supply voltage ranging from 10.5 V to 85 V with a
maximum current of 10 Arms.
In combination with the STEVAL-PCC009V2 evaluation board and the SPINFamily evaluation tool, the board provides a
complete and easy to use evaluation environment allowing the user to investigate all the features of powerSTEP01.
With daisy chain configuration support, the board is suitable for evaluation of multimotor applications.
