https://www.nxp.com/files-static/training_pdf/FTF/2012/americas/WBNR_FTF12_AUT_F0098.pdf has many cool pictures explaining the whole thing.

|
|
https://www.nxp.com/docs/en/application-note/AN4849.pdf is literaly a complete example of a four cylinder internal combustion engine (ICE) injector drive.
|
|
|
|
|
|
MC33816 has four independent microcores - four "threads" of execution.
|
|
|
|
One thread has to be controlling variable frequency modulation (VFM) DC-to-DC converter, whatever it means.
|
|
|
|
Two more threads are running two banks of two injectors each.
|
|
|
|
Each injector has it's own low-side driver.
|
|
Each bank/pair of injectors share a "boosting" - i.e. high-voltage opening high-side driver, and a "holding" - i.e normal battery voltage high-side driver. (page 59)
