Sales Briefcase
  • The EVAL-L9942 is the Evaluation Board designed to provide the user a platform to evaluate the device L9942.

    The L9942 is a motor driver for bipolar stepper motors with micro-stepping and programmable current profile look-up-table to allow a flexible adaptation of the motor characteristics and intended operating conditions.
    Different current profiles can be chosen depending on target criteria: audible noise, vibrations, rotation speed or torque.
    The decay mode used in PWM-current control circuit can be programmed to have slow, fast, mixed and auto-decay.
    The programmable stall detection is useful to avoid running the motor too long time in stall position minimizing the noise.
    The EVAL-L9942 board provides all the inputs and outputs capabilities necessary to drive correctly a bipolar stepper motor and also to monitoring diagnostic functionalities.
    The board can be connected to the discovery boards developed for the SPC56 microcontroller.

    主要特性

    • Input signal connector compatible with the SPC56 Discovery boards. Possibility to connect the board to further microcontroller discovery or control boards by a simple adaptor.
    • Two output terminal blocks.
    • Wide supply voltage range (VBatt): 7 V ÷ 20 V.
    • 2 LEDs for monitoring VBattand EN signal.
    • Device controlled and programmed via SPI.
    • L9942 diagnostic functions via SPI.
    • Test points to monitoring both input signals (SPI, PWM, EN, StepClock) and the four outputs (out power stage).
    • No heat-sink is required
