Note 2:
QFN and SOT-packaged parts are 100% tested at +25°C only and guaranteed by correlation at the full hot rated temperature.
Note 3:
The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in
this data sheet.
Note 4:
Guaranteed by design.

Note 6:
Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal range.
Note 7:
Leakage parameters are 100% tested at maximum rated hot temperature and guaranteed by correlation at +25°C.
