EVAL-L9177A EVAL-L9177A Evaluation Board Data brief Description The EVAL-L9177A is an Evaluation Board designed to evaluate L9177A, a smart power device designed by STMicroelectronics in advanced BCD technology. L9177A is able to drive all the relevant loads used in one/two cylinder powertrain applications (Injectors, Relay, stepper motor, tachometer, 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 (K-Line). Features All channels are protected against short circuit Voltage min/max: 3.9 V to 30 V. and over-temperature condition. No. channels: The board can be connected to the SPC563M- 2 injector driver DISP, the Discovery+ board developed for the 1 Lambda sensor heater SPC563M64L. 3 relay driver 1 LED/Lamp driver Table 1. Device summary Tachometer driver Order code Reference Stepper motor driver EVAL-L9177A 1 Protected High side dirver EVAL-L9177A Evaluation Board Device registers setting and the full diagnostic are available through SPI. Communication protocols: SPI, Kline. Access to all relevant pins by test points. Input signal connector compatible with the SPC563M-DISP (SPC563M64L Discovery+ evaluation board). Possibility to connect a generic microcontroller boards by using a simple adapter.
