MC33810 Injector and Ignition driver

Post by kneelo »

Any thoughts on use of a MC33810 IC to driver the injectors ignition outputs. These chips drive 4 high impedance injectors directly and are a pre-driver for IGBT's to drive 4 ignition coils.

I like the idea of this as it provides protection to these outputs as well as fault feedback useful for diagnosing problems. It has parallel inputs for each of the drivers and uses SPI for configuration and fault communication.

You would probably use a couple of these to provide 8 injection and ignition outputs?

I recall having once built a breakout board for this chip. I see some notes about it at the below link. I can't seem to find that breakout board. Perhaps lost to bit rot.

It's generally an OK chip. You need to pay attention to thermal, as you have the heat slug in the bottom. Other than that, I recall you can expect it to function OK for most applications.
Welcome to the friendlier side of internet crazy :)

Yes Subaru EG33 PnP board uses it for some years now, Dron has contributed the driver.

We also have a breakout module https://github.com/rusefi/rusefi-hardware/blob/main/MC33810-breakout/

Hello, which version of firmware should this board be used? Can you explain the hardware connection and software setting in detail? My current CPU chip is F407VET6 and I am looking forward to this chip being applied to the ECU
