AEK-MOT-SM81M1 Data brief Stepper motor driver evaluation board based on the L99SM81V for automotive applications 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 Description 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 Product summary 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 AutoDevKit stepper connector or two 5-pin connectors on the board. motor driver board AEK-MOT-SM81M1 for automotive The board is developed as part of the AutoDevKit initiative, and evaluation firmware applications is available for suitable microcontrollers such as the automotive-grade SPC5 series MCU on the AEK-MCU-C4MLIT1 control board. programmable stepper motor driver L99SM81V for automotive applications SPC5-Studio addon Development for Eclipse (with environment AutoDevKit plugin extension) Suggested SPC5 family MCUs microcontroller Automotive bipolar stepper motor e.g.: - adaptive vehicle Applications front lighting systems - vehicle HUD projectors DB3986 - Rev 1 - July 2019 www.st.com For further information contact your local STMicroelectronics sales office.AEK-MOT-SM81M1 Overview 1 Overview The AEK-MOT-SM81M1 board targets automotive applications such as adaptive front lighting systems and HUD projectors, with stepping resolution ranging from 4 full steps to 64 micro steps for the finest possible positional control. The L99SM81V driver logically manages timers, counters, reference tables and mode or status registers that are read or set by the external microcontroller to drive the two coil phases of a bipolar stepper motor, with separate RUN and HOLD profiles for moving the rotor or keeping it stationary. Apart from supply voltage and driver current diagnostics, the driver also monitors the output voltages across the phase terminals in order to detect and flag critical motor stall events that can compromise motor operation and control.
