TPS40055-EP TEMP RANGE

Louis Diana

Other Parts Discussed in Thread: TPS40055-EP, TPS5450-EP

TPS40055-EP storage temp range is specified at -55degC while TPS5450-EP is specified at -65degC.

Why the difference or is this a misprint?

Lou,

The EP datasheets are generated by the HiREL group. I am checking with them regarding the difference.

Lou,

Both devices have passed temperature cycle -65C to 150C, so both can support a storage temperature of -65C.

Both devices have been characterized to -55C, so both can operate at -55C, but cold temperature start-up can not be guarenteed at to -65C.
