产品概述
描述
The EVAL-L9958 is the simplest solution to evaluate L9958 functionalities providing all the inputs and outputs capabilities necessary to drive DC or Stepper motors and monitor diagnostic functions.
L9958 is fully integrated motor driver for DC and stepper motors used in safety critical applications and under extreme environmental conditions . It can operate from 4 Vmin to 28 Vmax delivering to the load up to 8.6A. The current regulation threshold can be set by SPI from 2.5A to 8.6A (Typ.) in 4 steps.Detailed failure diagnostics on each channel is provided via SPI: short circuit to battery, short circuit to ground, short circuit overload, over temperature. Open-load can be detected in ON condition, for the widest application ranges. The EVAL-L9958 board is suitable for both beginners and expert users working in standalone mode connected with any control system or combined with all SPC5 Discovery+ boards though a computer graphic interface or though embedded application examples.The board is compatible with both 5 V and 3.3 V control systems
