Recent testing has uncovered a problem with the FM18W08 at cold temperatures.
These parts meet the current datasheet specifications with the following exceptions:
-
All datasheet parameters are as specified provided the operating temperature is ≥ -15°C.
-
If -25°C minimum operating temperature is required, then you must comply with a minimum VDD Fall Time (tVF) of 200μs/V.
There is a design change in process to improve the cold temperature performance. An update will be issued when the design change has been verified.
