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.
