The AMIS-3052x/NCV7052x are micro-stepping motor drivers for bipolar stepper motors. These devices have a serial peripheral interface (SPI) and a dedicated error output pin, which can be connected to an external microcontroller. Advanced features for error diagnostics such as: open coil detection, short circuit protection and over temperature protection are embedded into the 52x. By using proper diagnostics routines, 100 percent of the single case open/shorts can be detected and handled.

This application note gives an overview of the failure modes that can occur in a stepper motor application and describes the coverage of the 52x for their detection. For specific error conditions, algorithms are described.
