The charge pump not being stable can mean several things. If it's not where it should be (it won't be) the high side fets won't turn on all the way, causing loads of excess heat inside the chip. This also may never recover, depending on the duty cycle, and then that chip will burn up/let the smoke out.

Essentially, the charge pump capacitor has a set of circuitry that brings the low side of it low, lets it get 5 or 12v, then floats it up to the voltage rail, to turn on the fet hard. If it's only partially on, the fet has a resistance that is too high. (The high side of the capacitor usually has a diode to charge it)

Right now? I'd say first alert smoke alarms. The batch we bought all has failed in an "alarm always, and don't stop" kind of way. They are only two years old, and I'm frustrated.

Are you sure you replaced the 5v regulator with a pin compatible one?

The tlv75733 is a linear regulator, so if you are giving it more voltage than it was set up for, it will get hot, as it has to soak up the difference.

Does the teensy act the same when powered by USB instead? If not, it's not the tlv.

Edit: the tlv has a thermal shutdown, so the shutdown is a direct result of the overheating.

It doesn't help that news corps have found that we generally respond to the negative news much more than we do positive news.
