Adjusted LM46000 to start-up at gt 12V instead of Vmin #8

Closed gbalke closed 4 years ago

gbalke commented 4 years ago

This will hopefully mitigate the issue of the current spike observed at start-up when using many motor controllers.

It also appears that one of the latest version of nightly changed the file extension for schematics to .kicad_sch so that's tagging along on this commit.

TODO before merging:

Update BOM
Generate Gerbers/Drill Files

Edit: Corrected voltage divider as mentioned below.

gbalke commented 4 years ago

Woke up and realized the voltage divider was wrong :sob: This is when you know you've spent too long away from circuit design... I'll swap out the 59k for a 47.5k which should give us an enable voltage of 12.075 Volts.

Currently Ven=14.49 which is a bit above what we'd like.

I just created a tag for REV 2.2 so we know what was fabricated before we update the design and especially gerber files. Let me know when all is fixed and ready for review!
