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 V Sx decreases, a fault occurs if V BAT – V Sx > V STG . STG threshold, V STG = V DTSTH + V STGOFF .
5 As V Sx increases, a fault occurs if V Sx – V LSS > V STB . STB threshold, V STB = V DTSTH + V STBOFF .
