STMicroelectronics EVAL-L9960T, Graphical User Interface (GUI) Evaluation Board With SPI for SPC56 discovery board

The STMicroelectronics EVAL-L9960T Graphical User Interface is the simplest solution to evaluate L9960T functionalities providing all the inputs and outputs capabilities necessary to drive DC motors and monitor diagnostic functions. The driving strategy is enhanced by configurable PWM/DIR pins as IN1/IN2.The H-Bridge contains integrated free-wheel diodes. In case of free-wheeling condition, the low side or the high side transistor is switched on in parallel of its diode to reduce power dissipation. The integrated Serial Peripheral Interface (SPI) allows device parameters adjustment and to control all operating modes and read out diagnostic information. Detailed failure diagnostics on each channel is provided via SPI: short circuit to a 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-L9960 and EVAL-L9960T boards are suitable for both beginners and expert users working in standalone mode connected with any control system or combined with all SPC5 Discovery+ boards through a computer graphic interface or through embedded application examples The board is compatible with both 5V and 3.3V control systems.
