Good to hear, I did not wish to cause panic, was just sharing my observation, the damaging of the mini-GT driver may not have anything to do with the 2mm white flat.
He should just use one of these. Is it really $10 stopping it or is there an issue with driver size and the D1S. He is hopefully redesigingim it a bit for a 21700 anyway.
Thank you Hank for an update. Itâs sad to learn you canât do it, but I like your openness.
I suggest that you look at Texas Commander driver. Itâs in a beta state. And may not deliver the current that you need. But using Led4Power trick of putting the FET on MCPCB should solve the issue and make it easily handle 5A, probably 8A for 2mm² variant as well. You would still have to put the work of taking it out of beta and into productionâŚbut it seems youâre more than capable of doing so.
It has to be an e-switch driver for the Emisars.
I think Lexel may have something available.
Iâm still waiting for led4powerâs e-switch version of his FET CC driverâŚ
But iirc Emisar uses 20mm drivers?
Either way, iâm guessing there are a few people on BLF who would be more than happy to come up with a suitable driver and PCB layout, if Hank canât find a solution.
Yep, the e-switch is the issue for those drivers. If the driver designers didn't take into account parasitic drain, an e-switch may never work on that driver design.
Again, our ramping UI's should work fine with a 7135 bank + 1, or even without the +1. I got NarsilM working on a FET only driver because the 7135's were constantly getting blown - yes, lots of amps for 16 XHP50's...
