Hello,
We are testing a part of our larger circuit separately. In the tested section, we have a INA180A2 which is supplied by an LDO at 5V. IN- is connected to GND of the IC and IN+ is connected to a sense resistor but there is NO bus voltage applied or load connected. Once the LDO is turned ON, the INA180 heats upto 100 degrees celcius and the voltage on IN- goes to 3.6V and IN+ goes to 3.85V, the output goes high too (4.2V). Please let us know if this is an incorrect way of testing or what might be the reason behind the part heating and voltage generation at IN pins.
