Hello,
My customer uses the INA194, monitoring a current of 24V supply line.
V+ is 5V, a external comparator trip level is 0.7V.
Power up sequence is as follows.
1. V+ = 5V ON
2. 24V supply line ON
According to the datasheet, output voltage is 1V(max.) before 24V supply line ON.
So, that value is over trip level.
The customer decide to change the power up sequence, has some questions.
Q1) Could you tell me the variation of the OUTPUT voltage due to the process variation?
It is only mentioned 300mV(typ.) on the datasheet.
Q2) Does it occur any output voltage when V+=0V and VCM is 24V?
Regards,
Naoki Aoyama
