Dear Team,
OPA197 is used in a circuit where during failure condition an undervoltage situation can happen. In this case the supply voltage collapses to about two volts. It can be observed that the Iq which is normally in the 1mA range increases to about 5mA in this case. The current is limited with 2.2kOhm resistor. After the failure condition is being resolved the OPA settles again and returns to normal operation.
My question is, in case the failure condition and the leaking 5mA occur for longer time (say a couple of hours) does this harm the silicon and has influence on the product lifetime. Will the OPA survive this condition?
many thanks
Lutz
