In the datasheet the "ton" spec for minimum CTRL pulse width to enable is 500uS. I've got an application where code was written targeting 500uS but due to tolerances the pulse could be as low as 457uS. The spec test conditions were for -40 to 85C. If actual operating range is 0-40C and voltage is 3V can there be any guarantee that the part will operate correctly or will software need to be re-written?
