I want to use the AD5372 in an area where a failure of the connected device might short the output of it to the positive or negative rail, or even its neighbor. Can it survive this or will it be damaged?
Yes I missed that - You're correct, the thermal shutdown feature would protect the part.Regards,
Once the part is not stress beyond the absolute maximum ratings (Table 5 in datasheet) the part should be fine. The main issue will be the effects of the part heating up most likely. The maximum short circuit current is 15mA. You can calculate the power dissipation that will be caused because of this short. If the junction temperature is exceeded you will damage the part.
Thanks for the response. I went and calculated the die temperature rise vs how many pins could be shorted. I'm using a 12V/-12V so depending on ambient temp shorting all of them could push past the 130C die temp limit. I have a question though, since this part has a thermal shutdown at 130C wouldn't that protect the part from being damaged?
