Stepper motor driver evaluation board based on the L99SM81V for automotive applications. This evaluation board is designed to drive a bipolar stepper motor in micro-stepping mode with coil voltage monitoring for stall detection. This application board features the automotive-grade L99SM81V stepper motor driver with embedded power MOSFETs and a comprehensive set of I/Os for MCU control and feedback signalling using SPI communication through a 12-pin male connector or two 5-pin connectors on the board. The board is developed as part of the AutoDevKit initiative and evaluation firmware is available for suitable microcontrollers such as the automotive-grade SPC5 series MCU on the AEK-MCU-C4MLIT1 control board.
