Product Overview

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.
  • Board reverse battery protection with STD95N4F3 MOSFET
  • Input operating voltage range from 6V to 28V
  • Output current up to 1.35A
  • Board size is 65mm length x 81mm width x 11mm maximum component height
  • All ST components are qualified automotive grade
  • Micro-stepping and hold functions
  • Suitable for automotive bipolar stepper motor applications
  • BEMF monitoring for stall detection
  • Programmable configuration via SPI
  • 5V internal linear voltage regulator (output available on board connector)
