Hi Experts,
Our customer has an old design from their company, they discover that the schematic deployed is not compliant with the SDLA006A information (Rex > 180k). Which can be the consequences? The circuit works as expected most of the time but they are afraid that some disagreements may occur sometimes.
Please advise. Thank you in advance for your information.
Best regards,
Gerald
Hi Gerald,
Are they using the commercial or the military device?
The datasheet indicates that the external timing resistance should not be greater than 180kohm for the military rated part:
We cannot guarantee correct operation with values outside the datasheet specification.
There will always be some leakage current into the device - large resistances can produce a significant voltage drop from this leakage current.
For an example, a 180kohm resistor would drop 1V from the supply if only 5.5uA were run through it.
