1_{Function is correct but parameters are not guaranteed above or below the general limits (7 to 28 V).}
2_{For input and output current specifications, negative current is defined as coming out of (sourcing) the specified device terminal.}
3_{Current Trip Point Error is the difference between the actual current trip point and the target current trip point, referred to maximum full scale (100%)}
current: E_ITRIP = 100 × (I_TRIP(Actual) – I_TRIP(Target)) / I_FullScale (%) .
4_{As VSx decreases, a fault occurs if VBAT – VSx > VSTG . STG threshold, VSTG = VDTSTH + VSTGOFF .}
5_{As VSx increases, a fault occurs if VSx – VLSS > VSTB . STB threshold, VSTB = VDTSTH + VSTBOFF .}
