I'm using my first TCA0372 as a ~1-2 Watt heater drive. Unfortunately
I've blown it up three times... twice by accident and this morning on purpose.
Apparently the TCA can't have it's output shorted to ground.
I_out max is 1.0 A (DC),

So I need either some output protection.. current limit. Or another
opamp that does ~100 mA, or I'll have to do some transistor pass element..
it's dead slow so speed is not important.
thoughts?
