STMicroelectronics Demonstration Board for L6470 for Voltage Mode Driving

The EVAL6470PD demonstration board is a fully integrated microstepping motor driver. In combination with the STEVAL-PCC009V2 communication board and SPIN evaluation software, the board allows the engineer to investigate all the features of the L6470 device. In particular, the board can be used to check the voltage mode driving and to regulate the L6470 parameters in order to fit the application requirements. The 4-layer layout and the PowerSO package allow the top thermal performance to be obtained. The EVAL6470PD supports the daisy chain configuration making it suitable for the evaluation of the L6470 in multi motor applications.
