ST whitepaper on GDI https://www.st.com/resource/en/white_paper/stmicroelectronics_enables_electronic_control_of_the_next_generation_of_gasoline_direct_injection_gdi_engines.pdf mentions L9781 https://www.st.com/en/automotive-analog-and-power/l9781.html which has not been mentioned on this forum so far.
Does anyone have the brains to compare the NXP solution to ST solution? Are there any other options on the marker?The L9781 is a multi valve pre-driver capable of driving 11 external N-channel logic level MOSFETs, controlling up to 5 inductive loads through peak and hold current control and one DC/DC step-up converter, providing full protection against accidental faults on the external hardware. The load peak and hold current control (together with the diagnosis) is done by the internal configurable Finite State Machines (FSMs) needing only the start of actuation commands from the main microcontroller.
