  • The EVAL-L9788 is an evaluation board designed to evaluate L9788, a smart power device designed by STMicroelectronics in advanced BCD technology.

    The L9788 is an integrated circuit designed for automotive engine management system. It is a device realized in ST BCD proprietary technology, able to provide the full set of power supplies and signal pre-processing peripherals needed to control a 4 cylindres internal combustion engine. All the device function configurations can be done via MSC configuration and 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.
