Notes

Production test at 125

°C is at VIGNP = 6.0 V. Operation to 26.5 V is guaranteed by design.

Guaranteed by characterization, not production tested.

Design Information, not production tested.

≤ VIGNP ≤ 26.5 V, unless otherwise noted. Typical values reflect the approximate parameter means at TA = 25°C under

nominal conditions, unless otherwise noted.
