Eval-L9779WD-SPI Eval-L9779WD-SPI Data brief Description The EVAL-L9779WD-SPI is an Evaluation Board designed to evaluate L9779WD-SPI, a smart power device designed by STMicroelectronics in advanced BCD6s technology. L9779WD-SPI is able to drive all the relevant loads used in powertrain applications (Injectors, Ignitions, Relay, etc.), to interface with Variable Reluctance Sensors and Hall sensors, to monitor diagnostic functionalities and to interact with the main networks present in powertrain environment Features (CAN, K-Line). Voltage min/max: 4.15V to 28V. All channels are protected against short circuit No. channels: and over-temperature condition. 4 injector driver The board can be connected to the SPC56M- 1 canister valve driver Discovery, the Discovery+ board developed for 2 Lambda sensor heater the SPC563M64L. 1 Main relay driver 6 relay driver Table 1. Device summary 1 LED driver Order codes Reference 4 Ignition driver EVAL-L9779WD-SPI EVAL-L9779WD-SPI A programmable power stage configurable as Evaluation board double H-bridge to drive a stepper motor driver, or as independent 4 High side and 4 Low side drivers. Device registers setting and the full diagnostic are available through SPI. Communication protocols: SPI, CAN, (both with dedicated connectors), Kline. Access to all relevant pins by test points.
