ESD protection diode in powerSTEP01

2021-11-23
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...

How to control multiple powerSTEP01 instances to move in synchronization?

2021-11-16
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 ...
