Hi Shawn,
To verify that the TEC is not shorting and hence casing the problem, I replaced the TEC with a power resistor, drawing about 0.7A. The same problem remains.
In all the testing done so far, I noticed that the DRV595 does not feel exceptionally hot to the touch, it measures about 30degC on the surface of the chip.
Any more ideas?
