Can High side Outputs drive VVT solenoids

[ElDominio]

Ask question states, can high side output drive a VVT solenoid that has one side wired to ground?

@ElDominio please provide context what pins are you asking about? ignition control pins I am sure are too weak

[ElDominio]

Internal High1 and High2, the ones on the molex microfit

@Qwerty-OFF needs your help

https://jlcpcb.com/partdetail/Pjsemi-PJM2319PSA%2FC411720#EC says 3A do we trust this 3A for PWM? is it just unprotected? Do we need to experiment?

[Qwerty-OFF]

Yes, we need an experiment. Perhaps long-term operation with a current of 3 Amps will cause significant heating. These outputs are unprotected. Flyback diodes are present, you can control the inductive load using PWM.

[ElDominio]

I don't think VVT solenoids ask for more than half an amp, so we should be fine?

[rusefillc]

we need an experiment

@ElDominio would you be able to make an experiment happen?

[ElDominio]

What is the experiment

[rusefillc]

@ElDominio please wire up a VVT solenoid on bench or real car and see what happens

[ElDominio]

This will be tested eventually

It may not be because #179 happened
