Hi,
From Ux625 datasheet, it is written
"The UC1625 is characterized for operation over the military temperature range of –55°C to +125°C, while the UC2625 is characterized from –40°C to +105°C and the UC3625 is characterized from 0°C to +70°C."
Is there someone who can explain me the definition of "characterized"?
Does it mean that:
- Chips are internally identical but during production, chips are more or less checked to guarantee that they will work correctly according the temperature range?
- There are internal electronic differences between each parts.. These differences explain why some parts are guaranteed to work correctly at different temperature.
I have this question because we would like to replace an obsolete UC1625L with a UC2625Q part. Our customer ask us to guarantee this change have no ECM impact.
So finally I would like to know if the internal electronic structure are identical between chips.
Regards,
Gilles
