EVAL-L9958 STMicroelectronics

EVAL-L9958 L9958 Evaluation board for high current (8.6A) DC and Stepper Motors Data brief Possibility to hardware setup EN, DI and DIR by jumpers No heat-sink is required Description 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 Features the load up to 8.6A. The current regulation threshold can be set by SPI from 2.5A to 8.6A Wide supply voltage range (VBatt): 4 V 28 (Typ.) in 4 steps.Detailed failure diagnostics on V each channel is provided via SPI: short circuit to Current regulation threshold set by SPI: 4 battery, short circuit to ground, short circuit levels from 2.5 A to 8.6 A (Typ.) overload, over temperature. Open-load can be Device controlled and programmed via SPI detected in ON condition, for the widest Diagnostic functions accessible via SPI: application ranges. The EVAL-L9958 board is short circuit to battery suitable for both beginners and expert users short circuit to ground working in standalone mode connected with any short circuit overload control system or combined with all SPC5 over temperature Discovery+ boards though a computer graphic open load interface or though embedded application On board 5V, 1.5A Voltage regulator examples.The board is compatible with both 5 V 2 LEDs for monitoring VBatt and EN signal and 3.3 V control systems Input signal connector compatible with the Table 1: Device summary SPC5 Discovery+ boards Order codes Reference Possibility to connect the board to microcontroller boards by a simple adaptor EVAL-L9958 EVAL-L9958 Evaluation board or by wires Test points to monitoring both input signals (SPI, PWM, EN) and outputs January 2015 DocID026696 Rev 2 1/6 www.st.com For further information contact your local STMicroelectronics sales office Contents EVAL-L9958 Contents 1 System requirements, HW and SW resources .............................. 3 1.1 Development tool chain ..................................................................... 3 1.2 Evaluation software ........................................................................... 4 2 Revision history .............................................................................. 5 2/6 DocID026696 Rev 2
