In the powerSTEP01 datasheet, it is mentioned that VSREG must be always less than VBOOT (and VCCREG must be always less than VCC) in order to avoid related ESD protection diode turn on. The device can be protected from this event by adding an externa...

I have recently purchased 4 X-Nucleo-IHM03A1 stepper motor driver expansion board. In my current project I am planning to use an FPGA to send SPI commands to the 4 boards to control 4 stepper motors to move simultaneously. May I know if there is any ...

Hi Sir, Thank you for the kind response. The step clock mode is not our design intent. Given that the same reference clock is connected to all of the powerSTEP01's OSCIN pin, but in the program we are still sending SPI commands (i.e. move(...
