Notes

15.

@ TA = 25°C, 14 V =< V+ =< 28 V, IO = 1.0 A.

16.

Typical value (for reference only) @ 85°C =< TJ =< 150°C, 8.0 V =< V+ =< 14 V. Not tested; not guaranteed.

17.

@ IF = 1.0 A for each output MOSFET (measured from source to drain).

Characteristics noted under conditions 8.0 V

≤ V

SUP ≤ 28 V, - 0°C ≤ T

A ≤ 85°C, GND = 0 V unless otherwise noted. Typical

values noted reflect the approximate parameter means at TA = 25°C under nominal conditions unless otherwise noted.
