Sales Briefcase
  • The AEK-MOT-SM81M1 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 signaling 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.

    Key Features

    • Board functionality based on L99SM81V programmable stepper motor driver for automotive applications:
      • with micro-stepping and hold functions
      • BEMF monitoring for stall detection
      • programmable configuration via SPI
      • 5 V internal linear voltage regulator (output available on board connector)
    • Board reverse battery protection with STD95N4F3 MOSFET, which can be substituted with two optionally mounted diodes and a jumper
    • Input operating voltage range from 6 V to 28 V
    • Output current up to 1.35 A
    • Board size: 65 mm length x 81 mm width x 11 mm maximum component height
    • WEEE and RoHS compliant
    • All ST components are qualified Automotive grade
    • Part of the AutoDevKit™ initiative
    • Applications: automotive bipolar stepper motor
