STMicroelectronics EVAL-L9788 Evaluation Board

STMicroelectronics EVAL-L9788 Evaluation Board is designed to provide the user with a set of tools for the evaluation of the L9788. The L9788 is a multifunction IC for an automotive engine management system. The STMicroelectronics board provides all the main input/output capabilities needed to drive all the supported loads and to interface with sensors providing diagnostic functionalities. All the device function configurations can be done via MSC configuration and a jumper on the board. All channels are protected against short-circuit, over-current, and over-temperature conditions. The board can be connected to the SPC563M-DISP, the Discovery+ board developed for the SPC563M64L.
