Hi, I've been studying electronic ignition circuits for some time because I want to build a circuit for my older motorcycle. Effectively I want to replace points and condenser with a gear tooth sensor on the existing points cam. Then use one of the nice igniter chips optionally running a more powerful coil.
The bike has 12v points ignition, a dual output 4.5Ω coil with wasted spark. On hand I have some BIP373 coil driver chips and 1GT101DC gear tooth sensor. The latter is too big to fit in situ but could be good for testing.
ATS616LSGTN-T looks like it would be a good choice for the hall sensor. I read of reports of success using it.
IRGB14C40L is another good looking choice for coil driver. I see it used IRGB14C40L circuit with apparent success.
I'm aware that I may have to invert the signal from the hall sensor depending if it goes high or low when it sees a tooth.
Is there any recommended circuits that would suit my needs? Keen to hear opinions, tips etc. Happy to supply more details.
Thanks.
