correctly, but parameters are not guaranteed, below the general limits (7 V).
2 See Gate Drive Timing diagrams.
3 For input and output current specifications, negative current is defined as coming out of (sourcing) the specified device pin.
4 As V Sx decreases, fault occurs if V BAT –V Sx > V STG . STG threshold, V STG = V DSTH + V STGO .
5 As V Sx increases, fault occurs if V Sx – V LSS > V STB . STB threshold, V STB = V DSTH +V STBO .
